investigation of the Nature of the Adhesion Bond in the Cementing of two
High-Molecular Compounds
The reaction of the substrata plays an important role. It is
highest in a neutral medium (Fig. 3) and is lowered when acid
or alkali solutioroare applied. This phenomenon is explained
by a reduction of the surface density of electrification.

ABSTRACT3 In a previous paper (Ref 1) the authors pointed out that the
adhesion bond between polymara may take place by two different
processes% (i) by the formation of an electric double layer at
the boundaries of both polymeral and (2) by diffusion
processes, in which case the boundary between the polymers is
blurred to an extent as to be aptly designated as contact zone*
There occurs not only a diffusion of chain segments and maoro-
molecule chains# but also a passage of whole structural
complexes.into the other molecule. Now experiments shoved that
also in this case an electric double layer is generated first.,
This was determined by means of a measuring device (Fig 1),
A metal plate was soldered onto the grid of a radio tubes Then

the changed grid potential caused a neon lamp inserted in the
circuit to extinguish. If both polymer surfaces are glued to
each other, the elootric double layer may be maintained in some
systems for an arbitrarily long time, whereas it vanishes
gradually in other systems owing to diffujion. The blurring of
the contact zone waa microscopically investigated at different
temperatures in the system gutta-percha - paraffin (Table 1).
Moreover, the diffusion process was investigated by marking
the one polymer with a luminophore (tropaeolin). The micro-
soopic preparations were photogra h d in the ultraviolet light.
The following was investigated:(1 geelatin - polyvinyl alcohol,
~2~ perchloro vinyl - gutta-porchap (3) gutta-percha - paraffin,
4 natural rubber - natural rubber (smoked shoots). The
photographs taken reveal that in some systems the boundary is
maintained (System I - Fig 2), whereas in other systems
diffusion occurs in the contact zone (system 3 - Fig 3P
System 4 - Fie 4). The authors thank T, At Krotoya and

ABSTRACT% In the introduction it is stated that the methods used hitherto
for investigating polymer adhesion are deficient. A now
"adhosiometor" is described which enables the determination of
the separating work of two bodies by means of an adjustable
velooityt and permits recording of voltage-oscillations during
separation* A scheme of this instrument is given in figure 1.
An electric resistance tensiometer is used for the determination
of voltage fluctuations. After a g9neral discussion of the
"adhesiometer" the experimental results are given. First, the
osoillograms shown in f1gure 3 of the systems gutta peroha -
steel# and other of cellulose plus bentyl alcohol - steel are
discussed. Subsequently, experiments are described which were
made in order to investigate the separation of tra telescoped
cylinders connected by a layer of polymers 200 - 300.At-thioks
Card 1/2 In these experiments the separation was recorded by means of a

cinematic camera, The change In voltage and in the distance
between the two cylinders is shown in two diagrams (Fig 4).
From results obtained in this manner the authors assume that a
separating stress may be d6terminal simultaneously with the
separating work. Tu. Me Kirillova, N. Ye. Golynakaya and

ABSTRACT: In reference i the authors observed that polymers severed from
glass surfaces in the course of changes in the reaction surface
reverse the sign of their charge. The present paper investigates
the relationship between the mechanical and electrical values of
adhesion to bases the chemioal character of which had been modi-
fied. The base employed consisted of glass the ourfsoe of which

ing off energy at a tearing off rate of 1 om/seo. The sign of
the charge of the torn off film was tested with a tube electro-
meter. The experimental results uhown in table 1 and figures 1-3
led the authors to the following conclusions: The reversal of
charge signs depends on the chemical composition of the surface.
Minimum adhesion is found-near the point of reversal of the
charge aign, Thus there is a direct relation between the mechan-
ioal and electrical adhesion values. The stated influence of a
chemical modification of the surface indicatea the importance of
the chemical factor in the formation of the oleotric double
layer. Since, according to the electrical theory of adhesion,
the charges of the surfaces torn asunder must be considered as
residual charges of the electric double layer, the reversal of
the charge sign of these separated Durfaces must be caused by
an equivalent revereal*in Wo cha*rge signs of the double layer.

ABST11ACT: The present paper, which was delivered as a report at
the IV Vsesoyuznaya konferentsiya po kolloidnoy khimii
(IV All-Union Conference of Colloidal Chemistr~) in
Tbilisi (1958), gives the results of a study of the
behavior of some oleophilic colloidal system near the
surface of a dielectric charged by friction, Objects
of the investigation were carbon-black suspensions in
vaseline oil and suspensions of printing inks and color-
ing dyes in machine oil. The investigation revealed
two basic processes in carbon-black suspensionssubject-
ed to the effect of the charged dielectric surface:

1) abrupt separating of large drops, which during
their movement assume a spherical form; diameter of
the drops 3-6 mm; 2) abrupt separating of small
drops, quickly following one another (at a medium
rate of 100 drops per sec?nd); the size of the drops
varies from 0.1 mm to 10- mm. Very often the forma-
tion of small drops (atomization) can be observed
immediately after.the fall of a large drop. Both pro-
cesses can alternate. Adding of a stabilizer (oleic,
acid) to the suspension does not affect its behavior
in the electric field. The deformation of small vo-
lumes of carbon-black suspension in vaseline oil (and
also of printing inks) under the effect of a uniformly
charged dielectric surface is explained by migration of
the charged particles of the disperse phase to the

surface, the particles entraining in their motion the
dispersion medium. In the absence of the disperse phase
the solvent (under the conditions of the experiment)
does not react to the approach of the charged surface.
When a sufficient number of charged particles has
accumulated at the droplet surface, it atomizes, owing
to repulsion of particles of the same sign and fall
in the surface tension. With the aid of high-speed photo-
graphy the authors measured the magnitudes of defor-
mation as function of the distance from the charged
surface, as well as the sizes and shapes of the atomi-
zing particles and the rate of atomization. The ob-
served phenomena may be utilized for contactless prin-
ting and electrostatic aerography. The authors mention

TEXT: In the present paper the authors give a detailed analysis
of previous studies on the bond formed by adhesion between
surfaces of various polymers and their critical evaluation is
followed by an account of the investigations, carried out at the
Institute of Physical Chemistry AS USSR. The study was made by
means of luminescence techniques because this method offers a number
of advantages in comparison with the more usual X-ray techniques.
Preliminary tests involved the introduction of a luminophor
(tropolin) into the solvent of one of the polymers in the
concentration of 1:20000. k film of the polymer with luminophor
was then formed on the surface of another polymer deposited on

the sub-base of hydrophobic glass. After the removal of the
solvent, the double layer of polymers was cut into a number of
small specimens for microscopic examination in UV light. The
tests showed that gelatine-gutta-percha polymers separation
boundary is clearly discernible and little diffusion occurs of one
polymer into the other. Data obtained in bond strength tests
showed that electric charges of opposite signs are present at the
separation boundary in the above system and that gelatine behaves
as an electron donor with respect to polyvinyl alcohol. Vinyl
perchloride behaves similarly with respect to gutta-percha.
Investigation of this production of electric charges on the surface
of polymer pairs during their separation showed that an electrical
double layer develops in all cases (including self-diffusion) in
the initial period of boundary separation. In some polymer
systems this double-laycr Is preserved indefinitely and, in others
it disappears in consequence of diffusion. Further studies were
made on an extended range of polymers including natural and
synthetic rubbers, paraffin and other materials. Full details are
also given of tests conducted with Belf-luminescent polymers. In
some cases, the separation boundaries of polymer pairs were heat-

cured before testing. The diffusion of the luminophor was found
to depend on the chemical nature of the polymers. The contact
boundary between identical polymers is very diffuse and
indicates self-adhesion. Self-adhesion occurs also in heat-cured
boundaries in the paraffin -gutta-percha system. Gelatine-vinyl
perchloride and other systems with polar groups have a sharp
separation boundary. In systems in which paraffin is one of the
components, the separation boundary is very sharp (0.061L) in
comparison with the diffusion range in other systems: 0.119 to
0.165 mm for the heat-cured gutta-percha- paraffin boundary.
Natural rubber- gutta-percha and similar systems have a wide
separation boundary characteristic of non-polar polymer pairs with
similar chemical structure and of other systems involving low
molecular weight paraffins. Systems with components with a clear
difference in their chemical structure (polar and non-polar), but
with characteristic polar groups present in one of the components,
gave a very narrow separation zone (micron and below). The vinyl
perchloride - C.Kra (SKB) system gave a sharp separation boundary
irrespective of the method of its preparation and the type of
thermal curing. It is suggested that the luminescence technique

is suitable for investigations of local stresses in microvolumes,
e.g. in the process of film formation, shrinkage and tearing.
In all these cases, bright luminescence is discernible. The
results of the investigation led the author to the conclusion that
the diffusion and electrostatic theories of adhesion are compatible.

TEXT: Infrared spectroscopy was used for examining the
interaction with glass surfaces of two types of polymers: with
inter- and intramolecular hydrogen bonds, the investigation being
based on an experimentally determined linear relationship between
the infrared absorption maxima and the distance between the proton
donors and acceptor atoms (Ref.3: K.Nakamoto, M.Margoshes,
R.E.Rundell, J. Am. Chem. Soc., 1955, 77, 6430). The glass
surfaces were specially prepared in or er to improve the adhesive
effect (pores varying from 40 to 1000 V Preliminary
investigations showed that the hydroxyl grOUPB on the glass
surface behave as adsorption centres for organic molecules

(metacrylic acid monomer). A comparative study was made of the
spectra of glass control specimens, previously dehydrogenated by
heating in vacuum, with those obtained for identical glass
specimens with a layer of adsorbed monomers which were
subsequently polymerized by heating. The polymers studied were~
para-carboethoxyphenylmetac,rylamide and ortho.-car-boethoxyphenyl-
metacrylamide. Adsorption of the monomers from the gaseous phase
gave spectra indicating hydrogen bonding between the hydroxyl
groups of the glass and the COOH groups of metacrylic acid. A
deeper chemical change occurs after prolonged contact of glass
surface with liquid monomer and leads to the disappearance of the
hydroxyl groups. Adhesive interaction of the para monomer with
hydroxyl groups gives a greater displacement of the OH absorption
band toward longer wavelengths than that observed in an analogous
interaction of the ortho compound. This points to a difference
in the distance between the 0 ... 0 atoms in the hydrogen bond
formed in these compounds. Differences in the width of
absorption bands of the ortho -and meta polymers indicate a
greater increase in the 0 ... 0 distance in the ortho polymers
with intramolef~ular h7drogen bonds. There are 6 figures and

of adhesion phenomena which are based on the formation of an electric
double layer. The mechanism of formation of this double layer is different
for different systems. The authors now investigate the character of
adhesive binding for semiconductors, dielectrics, and metals, and determineL

brought about by a magnetic mechanism. 'The fluctuations in tension are
recorded by electric resistance tonsiometers We The spectroscopic
invastigations of the samples were carried out with a spectrograph of the

Luminescence was also ihvoatigat*d. The adhesive binding of the following
systems was studiedl semiconductor - metal, polymer - &*mioonduotor,
polymer - glasep and polymer - polymer* The investigations showodg inter
aliag that the adhesion between indium and germanium substantially increases
if the surface of the latter has previously boon subjected to a Clow
discharge, The inoreass'of adhesion may be explained as being due to the
ppearanas of a large number of adhesion-active recombination conterst

observed. Theme results are in agreement with those of V. P. Smilga and,
B. V. Deryagin (DAN SSSR, 122,v. 6, 1049, 1958) who.'have shown that the
field at the junction of Geo'somioonductor and the metal increases rapidly
with an increase in the number of ionized centers at the surface of 2the

directly proportional to the number of surface states which, in their
turn, are related to the number of ionised centers on the free surface of
the semiconductor. In the oases invostigatedl the establishment of an
adhesive binding between polymer and glass is due to the appearance of a
hydrogen bond between the hydroxyls of the glass &ad the functional
groups of the polymer. On breaking the contact the glass surface is
found to be protonized while'the polymer surface emits electrons. Prom
this, it may be concluded that the total statistical effect that
accompanies the destruction of the hydrogen bonds acting in the inter-
facial plane gives rise predominantly to positive charges on the glass-,
oauved by protons of the broken bonds. The establishment of an adhesive
binding between two polymers is introduced by electrostatic processes.
Thereupon, diffusion processes take place on the interface, as was shown
by luminescence studies. The interface is blurred, and on separating the
two polymers no further electrical phenomena appear. T. A. Sokolova and
L. A. Oveyannikova are mentioned. There are 5 figures, 4 tables,and

TEXTs The adsorption proevas occurring at polymer-somiconduotok--fnter-
faces was investigated by measuring the surface conductivity in the "field
effe,at". The sample used was n-type germanium with a resistivity of
40 ohm:cm and a diffusion length of 2-5 mm etched in a H202-alkali mixture
and coated with films of linear vinyl-type polymers or methylmethacrylate-
methacrylic acid copolymers. The field applied had a strength of 106 V/Qm.
First, the surface conductivit.T was measured-in a sample of uncoated 091
here the Ad-versus-time curve showed a sharp rise when the field,was
appliedi followed quickly by-the minimum and returning then to the initial
value. On Go, two surface states were observedt the "fast" states at the
Go oxide - Ge interface and the "slow" states at the exterial-face of the
oxide or in the oxide. These slow surface states characterizing the'ad-
sorption and adhesion processes were studied by applying a constant

surface conduc 'tivity dependid'on the nature and concentration of the
functional groups. An incr6ase in the concentration of the CODH groups,
which are electron-donora, 6hinged the amount and the sign of the bending
of the bands and also the qyahtity and the sign of the charge resulting
from the adhesion bond between semiconductor and polymer. The experimental
data were compared with thoa~e'calculated from known theories. The impor-
tance of these investigations 'for the coating of simicoinductors is
stressed, There are 4 figures#

ABSTRACT: In order to determine the mechanism'of adhesion, several
i' phenomena at the polymer-solid substrate interface were investigatedc
Adhesive bonds resulting from diffusion processos in which the in-
terface is eroded, from the formation of a new phase on the sub-
strate by the polymerization of organometallic compounds, and from
chemosorption on the interface leading to the formation of a double
electric layer are discussed. By IR spectroscopy it has been
established that adhesion of polymers is largely due to chemical

donor-acceptor interactions. The adhesion can therefore be control-'
led by rational selection of the function groups of the adhesive
and substrate on the basis of their donor-acceptor properties. A
number of functional polymer groups were arranged in series accor I
ing to their ability to impart a positive charge to the surface on
tearing the film from the substrate (i.e., decrease in their donor
properties). A method was worked out for determining the effect of
the functional groups of the polymer by measuring the intensi-w of
electron emission formed by the breakdown of the adhesion bond
between the polymer and the glass substrate (figs. 1 and 2)'. There
are changes in the characteristics of a semiconductor upon formation
of adhesion bonds between it and the polymer; the part played by
the functional groups of the polymer responsible for the degree of
charge of the surface was investigated. The surface conductivity
in the field effect of germanium crystals modified with alkyl-
chlor'osilanes (fif, 3) was determined in an apparatus shown in tig.4.'

Variation of a over a wide range was considered so as to analyse
the function fst(s) in order to obtain information about the
;imits of variation of a in practical calculations.
Calculations were made on three discs: one of constant thickness,
another with a body of conical profile and a third with a body of
two sections, the inner conical and the outer of constant thickness
(Fig.2). The results plotted for different values of m, the
number of node diameters, show that the curves of fst(s) have not
more than two minima or inflection points. It was found that the
shape of the disc body has a considerable influence on the shape of
these curves and for a conical disc the influence of the hub is
not so great as for a disc of constant thickness, In order to
study the formation of these inflection points on the curve, for
one of the discs values were plotted proportional to the potential

energies of the hub, the disc body and the rim and it was found
that the shapes of the potential energy curves of the hub and body
have the most influence. The point in illustrated in Fig.3 which
shows the formation of minima on the curves of a for a flat-
conical disc where curve (1) corresponds to oscillation of the
body and curve (2) to the hub. The formation of two inflection
points, by super-position of the curves. is clearly seen.
Certain procedures are recommended for simplifying the calculations.
It is concluded that if a universal programme in available for the
digital computer "Ural". it in beat to calculate the natural
frequencies on the digital computer. The use of an analogue
computer is both less accurate and requires more preparatory work
for calculation of each fresh variant. Using A.V.Levin's method
of calculation requires 4 to 5 working days of manual labour
while the "Ural" computer can do the work in 30 to 60 minutes..
With manual calculation the minimum on the curve in determined
from 3 to 4 points and on the computer from 20 to 25 points.
