ABSTRACT: An ideal liquid is imagined to fill an open, rectangular vessel
which, suddenly, acquires a horizontal velocity. The problem is
plane. Issuing from the solution previously found by the author
for the hydrodynamic problem (Prikl. matem. i mekhan. , 1953,
Vol 17, Nr 4, pp 491-495; RzhM --kh, 195 3, Nr 3, abstract 1135)
the distribution of the impact pressures on a vertical wall;- is
computed. With a change in the ratio between the length 11 of the
vessel and the height 1,2 from zero to infinity, the position of the
center of pressure along the vertical wall varies from 0. 5 12 to

ABSTRACTs The author investigates a problem important for shipbuilding.~
the impact of an incompressible liquid against an in-.1ined irall.
The vessel which is enclosed by the inclined wall is partially
closed on the upper side. For the calculation of the ;roblem
it is assumed that the receptacle is infinf-tely long, and that
the whole problem can be considered to be plane. Up zj a
certain depth the recaptacle is filled with an incompressIble
and inviscid fluid. The lower side and the partially covered
upper side of the re,:ieptacle are horizontal and connected. i,-LTh
each other by an inclined wall (wall of a ship). The problem
is treated with the aid of complex.-analytic rnethods$ whereby
the cross section of the partially covered receptacle is
mapped onto the upper semiplane with the aid of a -:onformal
mapping. The problem is to find a velocity potential which
is connected with the pree3ure p and the density

ABSTRACT: This article deals with investigatinns based upon the mothod
of P. B. Bruns and 0. H. Frumkin [Ref, 53 which were conducted
by the authors for studying the mechanism cf sorption of
various inorganic and organic bases by means of active carbon.
Ash-free carbon of phenolaldehyde tar activated at a tempera-
ture of 900 - 10000C was used as an adsorber. Some strong

dissolved electrolyte does not only completely determine the
adsorptive behavior of hydroxides of alkaline and alkaline-
earth metals, but also plays an essential role in the
mechanism of sorption of the weak inorganic bases as piperi-

aniline and its derivatives are adsorbed by carbon in the
form of whole molecules. The basic results of this investi-
gation are shown by the table and by the diagram (1-3).

PERIODICAL: Kauchuk I Rezina, 1960, No. 3, PP. I - 5
TEM The aut1hor states that in the last decade synthetic rubber of high
elasticity was produced both by the USSR and the USA. A list of d,ome ~)f thle
typss which were synthesized is submitted (Refs. I - 7). it is p.:Amej ou, that,
all Iscpri-ne rubbers correspond to some degree to natural rubber., depending on
the nature of the catalyst and the polymerization method. Sir-r-3 was synthest?ed
in the USSR in 1957 - 1958. SKI-3 obtained with a complex moiified catalysts
was shown not to differ significantly in its microstructure from natural rubber
a-Rd SN Ameripol. It is quite similar to these in its technological and phyzico-
mechanical properties. The structure of the rubber was determined by the infra-
red spectroscopy method. k detailed description of the structure is given and
Table I shows the data of its comparison with natural rubber and Ameripol S11.
Its physico-mechanical properties are discussed. It was found that the SKI-3

rubber at a given composition vulcanizes at about the same ratA! as natural rubber
and in this way differs from the quickly-vulcanizing lithium-imoprene', rubber.
The elevated rate of vulcanization in the former is probably explain*d by the
pre---ence of residuall catalyst. SKI-3 is close to natural rubber in Its 'Vempera-
ture resistance (at 1000C). It was also found that rubbers produced with comp:ex
catalyst's have a more uniform structure, better technological properties Luid a
high-zi, temperature resistance, but their elastic dynamic properties are Inferior
to the hilgh-molecular lithium-isoprene rubber. The authors think that SKI-3 due
to its many valuable properties is of great significance to the -,ire and rubber

TEXTI In 1956, in the USSR the following polymer was synthesized using
complex catalystst Gis-lt4-diyinyl rubberl having a structure oft cis-10-
links 70%, trans-1,4-links 25% and 1,2-links 2-5% (Ref.12 and the following
properties: vitrification temperature of the polymer -1021C, molecular weight
35W00, unsaturation, 94-100%. Later on clivinyl polymers containing cis-1,4-
links up to 95rito were produced. In 1958 the possibility of obtaining regularly-
constructed divinyl rubbers using lithium as catalyst was proven. The 1,4-

authors deal with the properties of cis:1,4-aivinyl Mber obtained by the

the properties of lithium-clivinyl rubber. The properties of the regularly-

natural and divinyl rubber. The polymers synthesized with complex catalysts
(Ma-SKD) were found to have a more regular structure than thoae of the
lithium-divinyl type (CI?SIA-SKLD) . Table 2 gives an ind.1cation of these
structures and the respective vitrification temperatures. An outstanding
feature of the investigated divinyl rubbers is their high resistance to oxida-
tion destruction. The introduction of 1'/'~o phanyl-'P -naphthalamine insures a
satisfactory stability of this rubber in its processing and storage. Rubbers
of various molecular weight were obtained when using complex catalysts depend-
ing on the conditions of polymerization and, accordingly, different plasticity
(the plasticity varied from 0.10 to 0.70). The lithium-divinyl rubber under
the given conditions of polymerization was obtained with a high. molecular neight
only (plasticity.-O-05-0-10). The SKD-rubber can be satisfactorily processed
on laboratory equipment. During the rolling process it acquires a dense coat-
ing and is comparatively easily mixed with the ingredients. The SKLD-rubber
crumbles in the rolling process and without preliminary mastication cannot be
applied to the production of rubber mixtures. The mastication of divinyl
rubbers can be accomplished using chemical plasticizers. In the cast of the

SKLD-rubber the best plasticizer among those being tested proved to be an oxi-
dation-reduction system, consisting of "galipot" (boiled pine resin roCT 840-
41-GOST 840-41) and iron naphthanate. -The indicated system (at moderate
temperature (1300C) and in a relatively short period of tine, viz., X-30 min) was able
to raise the.plasticity of the rubber from 0,05-0-10 to 0-50-0-70- It is
further pointed out that the investigated rubbers, SKD and SKLD, have no acLhe-
sive properties. The technological properties of filled divinyl rubbers were
found to be unsatisfactory. The introduction of channel carbon black caused
the plasticity to drop, which ia explained by the fact that divinyl rubbers do
not destruoturalize during the mechanioal processing, contrary -to natural or
isoprene rubbers. The type of carbon black used was also found to have an
effect on the mixture. Mixtures containing Filbreck 110" carbon black have a
much better surface in calendering and atomizing than.those filled with gaseous
carbon black. Large quantities of softener or plasticizer are suggested to
improve the technological properties of filled divinyl rubber mixtures. The
vulcanizate properties of divinyl rubbers were studied by comparing them to t1uLt
of the industrial type divinyl rubbers: CH6 (SKB) , CRB (SKY-potassium-diTirtyl

rubber) and CRSM (SKBM-lithium-diyinyl rubber) having the same plasticity as
well as with natural rubber and divinyl- styrene rubber, CRC -30A (SKS-301) -
Carbon black-filled Yulcanizates were chosen for the inyestigation with respect
to the industrial type divinyl rubbers and SKLD. The tear-resistance of the
non-filled more regularly construated SKD polymers (ois~-lpij-linku 92-95M was
found to be higher and equal to 80 kg/CM2. Table 4 presents the comparative
figures of the physico-mechanical properties of the carbon black Yulcanizates
of the divinyl rubbers and that of natural rubber. It can be seen that the
indicated divinyl rubbers are close to natural rubber in their elastic-dynamio
properties and are superior in their wear-, frost-, and heat-roisistance. The
residual elongation of the divinyl rubbers decreases with an increase of the
cis-10-link content, which is assumed to be connected with the relaxation
phenomena. The temperature stability of all divinyl rubbers including that of
SKD is lower than that of natural rubber. The figures are actually misleading
since the testing of the divinyl rubber as compared to natural rubber is
conducted at higher temperatures, if the zero point is taken at the vitrifica,
tion temperature. The highest frost-resistance was found to be in SKD and

SKLD rubbers, which corresponds to their lower Titrification temperature. At
a.tqmperature of 200C the elasticity of the SKD rubber is much higher than
that of the natural rubber with the same carbon black content in the mixture.
The SXD and SKLD rubbers have a higher elastioity than tho SKS-30A. Since the
elasticity of. SXD, SKLD and natural rubber at elevated temperatTarea is almost
the same, the heat formation and mechanioal losses of the vulcanizates of
these rubbers are close. The vulcanizates of the SKD and SKLD rubbers retain
their elastic and resistance properties well after heat aging.(Table 6), which
is a great advantage of the divinyl rubber as compared to the natural rubber.
One of the greatest advantages of the regularly-constructed divinyl rubbers
is their high wear-resistance, which, in turn, is higher in SKD than in SXLD.
Finally, the SKD rubber has a high resistance to crack growth, determined
according to the method of H.E. Railsback. ftnluling, the author emphasizes
agaJn all the valuable properties of the regularly-constructed divinyl polymers,
stating that these properties of the cis-divinyl rubber make it applicable
as a rubber for general use by itself or in a mixture vrith natural rubber
primarily for the tire industry or for frost-resistant articles. The authors

50~6. This specimen was termed A-950. Its heating in nitrogen to 1750,
2000, and 23000C resulted in the specimens A-1750, A-2000, A-2300. A-3000
was obtained by heating in an electric resistance furnace of the type
Pr, -100 (RS-100). Reduction in weight was 3.21% at 175000, 3.50% at
20000C, 5.53% at 23000C, and 5.57% at 30000C. Debye-Soberrer patterns
were taken by means of a BPC,-3 (VRS-3) camera; the parameters La and L.
of the carbon arystallites were determined according to R. E.'Warren
(Ref. 13) and the radiographic density q was calculated from equation

unit cell along axis o). Table I indicates the data obtained. The
adsorption properties of the specimens were determined in a wide range of
relative pressure by means of a sorption balance for benzene, cyalohexane,
and water at 200C (Table 2). The cenetante of the ii3othermal lines of

corresponds to the maximum dooupation of the ddeorption volume WO and v
is the voluae of 1 millimole of the adsorbed substance (Table 3). This
carbon has a mixed structural type with two kinds of micropores as shown
in Fig. 5 for benzene and A-1750- In the miaropores of the first type,
which correspond to a6, there occurs an increase of the adsorption
potential. This effect is absent in large mioropores of -the second type
(all). The following relation has been obtained: ao' + all = a0 (6).
0 0
a0 is the adsorption occurring at the beginning of hysteresis and
capillary condensation of the vapor in the intermediate pores. This valu
is represented in Fig. 5 by a.broken vertical line: (p/ps)o - 0.175. Bas:d
an the sorption isotherm, the volumes of the different typea of pores were
evaluated: v + Vol are the volumes of the tWO ty])GB of micropores;

according to Brunauer, Emmett and Teller, and LangmtUr (Table 8). An
attempt hash been made to explain the structure by the example of A-~950-
It is assumed that binary micropores are formed by tho combustion of two
superposed crystallites when the carbon is heated. 4 is assumed to be the
specific surface of,the mioropores composed of the surfacl3 cc of the single
miaropores and of l-a of the "binary" ones. In the singla micropores, ni
molecules of one vapor and n~ molecules of another vapor are assumed to be
adsorbed. Correspondingly, nil, n" molecules are adsorbed in the binary
pores. "ll, 02 Pre assumed to 1 be 2 the areas oooupied by -the adsorbed

units. The final identification of each component was carried out by meam!3
of Raman spectra. 117 compounds,i.e. about 77% of the me"hane-naphthenic con-
centrate were identified and some regularities observed. It was observed
that naphthenes contain only 12% compounds with quaternary carbon atoms,
while paraffinic contain 29.0%. Naphthenes with quaternary atorlis are apparent-
ly less stable in liquid-phase hydrogenation*. Aromat-1c hydrocarbons were
separated in the present study chromatographically and thimi by fractional
distillation into 34 fractions. 14 compounds were identified by means of
Raman spectra Fon al4CII-51 (ISP-51) device] and ultraviolet spec',ra Fon a
