ABSTRACT In a previous paper it was shown that high pressure accelerates
the polymerization of 2,3 dimethyl-butaA.-2 (henceforth refereed
as DMB) considerably. In the present paper the authors,inte~nded
to study the oinetios of 293 DMB-2 and'of related eompo-ands at
high pressure and to investigate the properties of the poly-mers.
This reaction takes place gradually under a pressure of'3660-36ao
atm and at.a temperature of 290-29200 an'l passes through a dimer
state (which has its maximum yield after about 16 hrs).,The-dimer
fraction is able to undergo further polymerization. The degree
of polymerization after 32 hrs is still low (9,1-17,7%)- Unaer
the same conditions 2,3-DMB-i and 3#3-DhW-1 are polyzerzated

The polymers of the threo'hexanes undei discussionp which are

the authors carried out polymerization expeirimants with a .

to separate polymerization of either hexane. In the case of~ 'small
admixtures of the latter hexane to the former these effe'otsiare
not observed. This is indicative of a co-polynerization.; a fact,
which is confirmed by the values of theAlffraction coefficient
and by the specific weight. No formation talkee place, %herefore,
of a simple mixture of the polymers of both hexanes. Consequent-
ly the polymerization of 293-DIO-2 does not pass throu8h a

of the three hexames underloonsideratioh, as etructural:poly-

Cis-dalkylethylenes could not be expecied. They predominate,
however, in the dimer fraction. Moreover, the formation'of nono-

that in the case of the polymerization of 20 DMB-2 it is not
the molecules or the radicals of the monomeres that are'aubjekt

TOPIC TAGS: pressure effect, radical polymerization, acrylonitrile
ABSTRACT: The authors, having found that pressure has an unusual effect on
heterogeneous radical polymerization of acrylonitrile. e.g. . an increase of ~pres-
are from atmospheric to 2000 kg/cmZ at 50C leads to a decrease of the rat.ciot
polymerization and molecular weight of the polymer by a factox of 2.5 and 102
respectively, attempted to obtain darta on the effect of pressure on homogen eous
polymerization of acrylonitrile. This article gives the results of an investigation
of polymerization of acrylonitrile in a solution of dim ethyliorm amid e init" t d by
dinitrile of azoisobutyric acid at atmospheric pressure and at Z000 kg/CM2-. The
experiment demonstrated that the rate of homogeneous radical polymerizatio of
acrylonitrile in dimethy1formamide at 50C, unlike heterog eneous radical

polymerization of acrylanitrile, increases with an increase,of :pressure from
atmospheric to 2000 kg/cm?- by a factor of 4 and the average molecular weight of
the polymer by a factor of 1.5. The authors explain the cori,-Wratively small
increase of molecular weight at 2000 kg/cmZ by the fact that in the studied system
an appreciable role is played by the reaction of chain transfer through dimethyl-'
formamide and this reaction is accelerated by pressure almost to the same extent
as the reaction of chain growth. Orig. art, has: I figure and I table.

ABSTRACTS. Radical polymerization of styrenes initiated with azoisobutyrodinitrilesi
was studied at pressures up to 2000 kg/~2 in benzenes butyrall ydes-and tH irl mix-
tures at 500C. The rate and average degree of polymerization in benzene solution in-
crease by factors of 4.2 and 6*5 respeetiv-,.)ly as the pressure is raised from atmo-
spheric to 2000 kg/cm2. The effect of pressure decreases,with Increasing butyralde-
hyda content of the mixture, On the basis of data on the infLuencej of pressure on
the rate and average degree of polymerization of #yTene in bmene, the value of the
volume activation effect durin initiation (4 V J) at atmospheric pressure was cal-
culatede This value (+7.4 cm3IMI) was found to go close to that reported in the lit-

tio'n of radio waves according to data from j2n~s Abservations for 1962 (relatively low
~heAc
solar activity: 7 = 37.6). Hourly f min readings at 28 northern hemisphere stations served as
the~.:primary data base. The da~~ocessing and resea~Tc.h method was that of G_ N-Gorbushim-
(Gebmagn. I aeronomiya, 1 62, 2, io_._2_ 267), who made a similar study for 1958i The fre-
quency of anomalous abso: plion. occurren'ce was defined as the ratio (in.percentages) of the

observations. Estimatidn of the level of anomalous absorption In relative units permitted some
reauction of the effect of differences In Ionosphere probing equipment at the different stations.
Th" results of the calculations were used to plot the frequency, (totaled for all the days) of the
oc%Lrrence of anomalous absorption as a function of the corrected geomagnetic latitude of the
o~strvation centers. An overall shift from 650 to 670 for maximum occurrence frequency was
oVerved. Longitude has negligible effect on overall absorption patterns, with the result that
t~optiftklinal function of anomalous absorption occurrence can be useA for any longitude Orig,

(0.09 to 0.24 %). At 6500C and a degree of deformation.of
75 % the outflow pressure increases by,about 60 %. For
uranium in the If-phase outflow pressure decreases from
4 kg/mm2 at 8300C to 1.8 kg/mm2 at 10500C.
Ultimate strength and creep strength increase with an increas-
ing carbon content in the uranium. In hot-rolled uranium.with
a C-content of 0.01 % ultimate strength is d b - 36 kg/=21.in
uranium with 0.24 % C-content 6 b - 52 kg/iam?. The creep
strengths in these cases amount to 23 to 3'1 kg/MM2.

TEXT: Flat specimens of identical shape, and overall length 100 mm
(length~of working portion 40 mm, width 8 mm, -thickness 2;mm), made
from uranium, aluminumt zinc and from copper-zinc alloys,of diffe-
rent compositionsp were used for the investigation. The uranium spe.
cimens were tested without protection against oxidationp:heating of
being carried out in air and quenching in,:watero The specimens were
subjected to cyclic heat treatment in the temperature ranges 180

of specimens were controlled at these points by.:means-of thermoooup-
lee welded onto the specimens. The magnitude of the;residual,defor-
mation of the specimens was determined (1) after cyclic heat treat-
ment without application of external load; (2) after cyclic heat
treatment with application of a tensile load during,the heat treat-
ment cycle; (3) after creep tests at a temperature equal to the up-
per temperature of the cycle. The duration of the latter tests was
that of the full period of the heat treatment cyclev multiplied by
the number of cycles (the load during cyclic thermal treatment: under
load and in the creep tests being identical).,Tex-turized uranium
