and iron content - 0;15 - 0.311%. The res ulting 81943-30 ARM-15 commercial rubber
is characterized by the absence of noticeable quantities of high-molecular frac-;
tions. it is similar to SKS-30 ARM-15 and SKMS-30 AIRM 15 in its plastic properties
mix scorching and spraying resistance. Studies have been conducted on the possibi-
lity of further reducing -the emulsifier quantity in the production of butadievie,;
-styrene and butadienemethylstyrene rubbers. It was found that: a) by -reducing
the emulsifier quantity from 5.8 to 5.2 weight parts, the polymerization duration
does not change; b) by reducing the emulsifier quantity from 5.8 to 4.8 w.p., the
duration remains the same if the trilon B is increased from.0.04 to 0.05 w.P.

TEXTs The sizes of macromolecules of highly branched potanaium butadiene
dubber and of linear cis-polybutadiene (the latter being prepared in the
presence of a complex catalyst),were investigqted using a light-scattering
method. Both in solvents with nearly ideal thermodynamic properties and in
relatively good solvents aggregation of the diasolved macromolecules was
observed. The molecular weights and th'e mean-square radii of the polymer
clusters were determined with the polarization nephelometer and a photo-,
metric device described by V.-H. Tsvetkov et al. (ZhETF, v. 26, 245 (1954))-
In addition, the number-averaget molecular weight a Vn were determined by
the osmotic pressure method and the characteristic viscosities were measi~nd

TITLE: Vulcanization of methylsiloxane rubber with a low vinyl group con-
tent, under action of x -emission
PERIODICAL: Kauchuk i rezina, no. 12, 1961, 1 - 7
TEXT: An investigation was conducted to determine the conditions for
producing highly heat-resistant radiation vulcanizates of the CKTB (SKTV) rub-
ber. The possibility was studied for producing rubbers of even higher heat-
resistance by introducing compounds into the rubber mix which would increase
the magnitude of the intermolecular action in the system and the effective ten-
sility of the bonds in the vuleanizates, as well as by changing the conditions
of emission. Laboratory samples of methylvinylsiloxane SKTV-0.07 rubber, with
a molecular weight of 400 - 500 thousand, were investigated. The energy of the
7 -emission dose was held within the limits of 0.28 to 0.72 Mr/h. A study of
the tensility of the T-emission vulcanizates of the SMT-0-07 rubben filled
with various silica gels and carbon blacks, showed that the introduction ofmeet-

als with varying valencies into the silica gel filled rubber mixes increases
the physico-meclienical indices considerably. Preliminary refining of the rub-
ber mixes further increases the physico-mechanical indices. Experiments showed
that rubbers, retaining satisfactory tensile and'elastic properties, can be
produced from the above-mentioned sample, after thermal aging at a temperature
of 3800C. The additional increase of the heat-resistance in the given rubbers
is achieved by radiation vulcanization in a vacuum and by introducing a halo-
genated polymer into the rubber mixture. In the latter case, vulcanizates are
produced which retain satisfactory tensility and elasticity after short-time
aging at 4000C. A study of the effect of metal compounds of varying valencies
and of the halogenated polymer after introduction into the rubber mix revealed
that the former, being centers of secondary electron radiation, lead to the
formation of more regular vulcanization network and, subsequently, to a further
increase in the heat-resistancE If the radiation vulcanizates. The SKTV radia-
tion vuleanizates show a characteristic intensified destruction in the initial
period of the thermal aging, which is thought to be connected with the presence
of a certain number of weak oxygen-containing transverse bonds of the
C - 0 - 0 - C - type in the radiation vulcanizates. These bonds, in turn,

are formed through the reaction of oxidation of the molecular chains of the po-
lysiloxanes under the action of irradiation. The radiation vulcanizates of the
SKTV-0.07 rubber were found to exceed corresponding peroxide vulcanizates in
their heat-resistance and thermal stability in a closed system at 200 and 2500C
and at increased pressure. The former have a lower residual deformation after
compression at 150 - 2500C and a somewhat higher frost-resistance. There are 5

radical. A new macromolecular starts growing, and the polymer chain With
the Al atom at the end enters into solution,. Polymer chains with Al atoms
at the end are also formed in the spontaneous dissociation of the catalyst
complex at the bridge bond. The dependence of the polymerization rate of
isoprene on the composition of the organoaluminum compounds is explained
as a consequence of its direct participation in the polymerization. This
dependence p&rticularly occurs at low temperatures at which the further
reduction of titanium is inhibited by trialkyl aluminum. The different
polymerization rates of isoprene may be a consequence of the different
adsorption capacity of Al(iso-C 4H 9)3 and A1C1(iso-C 4H 9)2 on the surface of
P-TiCl 3 or of the different electron density of the bonds Al 0 in the

TITLE: Type and stability of crosslinks in radiation vulcanizates
of polysiloxane rubber
PERIODICAL: Akademiya nauk SSM Doklady, v. 139, no. 3, 1961, 651-653
TEXT: The authors had previously established that irradiated vulcanization
of polydimethyl siloxane rubber CKT (S'KT; leads to higher thermal stability
of the rubber obtained (Kauohuk i rezina,19, no. 9, 5 (1960)). The same
occurs in the case of polymethyl vinyl siloxane rubber CKTB (SKTV) with a
content of about 0.1 % vinyl groups. The thermal stability of vulcanIzates
developed through irradiation may be increased by previous addition of
metal compounds of variable valenoy or S102. This thermal stability

the presence of especially active radicals, but it is also linked with the
structure of the network of the vuloanizates developed through irradiation.

vulcanization of polydimethyl siloxanes, -)SI-C1~7CH2-S'e~Z is to be assumed
as the basic type of crosslinks for radiation vulcanizates which develop by
recombination of frAA 4 Ri -CH3 radicals This difference contributes to
the increase in thermal stability, both due to higher stability of the
C- C bond compared with the Si -Si or Si -C bond, and to formation of double
bonds at higher temperatures after the reaction

where no break of crosslinks and no destruction of radiation vulcanizates
occurs. Longer CH 2 chains may be formed during vulcanization of SKTV

structure of the network as compared with peroxide vulcanizates are
obtained by irradiation. Similar results were obtained with experiments In

TITLE: Polymerization n-P nitroethylene under the action of y-radi-
ation
PERIODICAL: Doklady Akademii nauk SSSR, v. 138, no. 3, 1961, 619-620
TEXT: The authors devised methods for the industrial production of high-
molecular nitroethylene under the action of y-radiation since in this case
products are obtained which are as pure as the initial monomers. Other
methods with initiator and solvent yielded 8o far only powdery products
contaminated by initiator and solvent. Co6 was used as radiation source,
the apparatus is described by A. Kh. Breger et.al. (Ref. 9: Deystviye V)~
ioniziruyushchikb izlucheniy na neorganicheskiye i organicheskiye polimer-
nyye sistemy (_'-fect of ionizing radiation on inorganic and organic poly-
mer systems), Izd. AN SSSR, 1958). The initial nitroethylene was obtained
by dehydration of 1-nitro-ethanol-2 with phthalic anhydride. Fractions
with a boiling point of 360C/100 mm Hg were isolated from the monomer by

repeated fractionation. Hot nitrogen was bubbled through glass ampuls
which were then filled with freshly distilled nitroethylene. The oc-
cluded atmospheric oxygen was removed by the usual freezing up and melt-
ing. The ampuls sealed in vacuo were irradiated at 200C, and the monomer
was distilled off in vacuo after opening. At the beginning of irradiation
(dose I - 106r), a turbidity was observed in the monomer which had hither-
to been as clear as water. At a dose of 5 - 10 6r a white precipitate re-
sults which is identical with the polymer resulting under the action of
organic bases. On further irradiation, the pasty monomer-polymer mixture
is converted to a transparent, pale-yellow polymer block. This is appar-
ently related to secondary addition reactions of growing polymer chains
to the polymer already formed, and is accompanied by an increase of its
molecular weight. At doses > 0.3 Mr/hr no block polymer is formed. In
this case the polymer remains powdery up to a 100% conversion, and turns
light-brown. The formation of the block polymer being a very complicated
physico-chemical process depending on many factors, a powder is formed in
some cases even with a 100% conversion. The polymerization of partly

polymerized samples continues also after irradiation is finished. This
suggests the formation of rather long-live polymer radicals under the ac-
tion of 7-radiation (Fig. 2). Also in this case block-polynitroethylene
results. The polymerization is inhibited by hydroquinone and oxygen which
confirms the radical nature of this process. The polymer is insoluble in
common solvents, well soluble in N,N-dimethyl formamide. Its intrinsic
viscosity in this solvent is 0.38 which corresponds to a molecular weight
of 38,000. Its density is d 20 1,535, the decomposition temperature 150OC-
No denitrification (- CH 2 -CHNO2)n takes place during irradiation. The
crystalline phase is absent (X-ray data by S. G. Strunskiy). An intense
narrow halo and a weak broad halo correspond to the parameters of the
short-range order 5-15 2 and 3.73 1. Under the action of I-radiation
nitroethylene may be copolymerized with other unsaturated nitro compounds
such as 1,4-dinitro-butadiene-1,3. There are 3 figures and 9 references:

Abstract The uninterrupted use of the chernozem soils for grain
crops at the Kellerovkiy Auxiliary Site for 5 straight
years caused a marked worsening in the soil structure.
The effect of different methods of working the soil was
tried out on the condition'of soil structure. Non-terra-
cing plowing in comparison with other methods of tilling
brought about less disruption of the water proof aggreg%-
tes larger than 0.25 nm. The greatest moisture in the
soil, horizons was also observed with non-terraced ploiring.

Orig Pub :Dokl. Mosk. s.-k-ho akad. im. K.A. Timiryazeva., 1957, vyp.,
29, 202-207
Abstract : Research made in Kokchetavslmya and Saratovskaya Oblasts has
shown that excessive moisture in solonetz and soloth soi I s
reduces the quantity of aerobic saprophitic microorganism,
the nitrifying and aerobic cellulose-decomposing bacteria,
while increasing the amount of anaerobic microorganisms.
Under anaerobic conditions the microbiological processes lead
to the formation of ferrous corVoundso The intensity of these
processes depends on the composition of organic substances,
as well as on the quantity of diverse species of microorganisms.

TEXT: Thequick-acting GRBI-1-2 gravity gradientometer contains an
Eotvos torsion balance, though this has a very small lever arm.
Thanks to the presence of extremely strongdamping, the instrument's
torsion systems are damped in the equilibrium position in 2 - 3
min. The gradientometer measures only the horizontal gravity com-
rD
ponents Uxz and Uyz- The gradientometer's accuracy is + 5 eotvos
units. Its productivity exceeds that for variometer surveying by
5- to 7-fold. A leveling set, which allows the productivity of
work on-allowing for the topography to be increased by 6 - 8 times,
--was developed at the same time as the GIM-2 gradientometer. The

consists of a self-adjusting d:i:optic level, a Samsonov rod conver-

TOPIC TAGS: petroleip product# corrosion inhibitors steel, CZfVW-q-r--
ABSTRACT: Ozocerite and petrolatum-base corrosion inhibitors ire now made by oxidu~iLn
with air at 130-160C in the presence of a catalyst. The preparation takes 10-24 hr.
A less time-consuming method was offered for producing a corrosion inhibitor from
petrolatum, It consisted of treating petrolatum with a 62% MIO solution, neutralizing
the reaction product with a 20% aqueous solution of NaOH withoat removal of the spent
IM03, and dehydration. The nitrated and neutralized petrolatum was completely solublQ
in oil and insoluble in waterg The test on the corrosion-protective properties of the
5% solution of nitrated petrolatum in transformer oil made with St.45 steel proved tha
as a corrosion inhibitor, the product was not inferior, if not superiors to the oxidized
petrolatum. The optimal con!!~mption of M02 was determined as 10%, Nitrating petrolatun!
with large amounts of h7i33(:!~E.30%) contributed in some cases to its corrosive propertiesi.-

1(5-15%)of 62,',~ F,403with noutralization byNa0H and dehydration yielded an inhibitor
.soluble both in wa6er and in oils. This permitted it to be used in the form of either
toil or water solutions. The most effective corrosion inhibitors for the steel was the
oxidized petrolatump hwiving an acid number of 30--~+15 after treatment with 15% addition
I solution. The quality of the inhibitors depended greatly on the yarity
,of the 62% B'03
of the final product. For this purpose the nitrated oxidized petrolatum was purified
Of spent Bh'03 by settling and treated with NaOH to a neutral reaction& The product of
nitration of oxidized petrolatum was tested as a corrosion inhibitor for ferrous and
nonferrous metals (Al., duraluminj CupPbv Sns bronzes Mg alloys., steelsp solder., cast
iron, and in combinations of metal-wood and metal-rubber). In all cases it provi-,.ed for
long-lasting and reliable protection. The nitration of oxidized petrolatum from the
Kazan NPZ was made in a pilot plant installation with 62% HNO (consumption 15%) at
70-90C for 4 hr without settling out any of the spent HN1030 Pne nitrated product had
an acid number of 90 mg KOH. The final neutralized inhibit6r had an ash content of 705%
an alkalinity by phenolphthalein of 1,2 mg KOH and by bromophenol blue of 65.7 mg KOH.,
a water content of 1s,6% Dean and Stark, and good protective properties of the 5% solu-
tionin transformer oil for St.45 steel: more than 30 days in water before the appearano
of corrosion nuclei. The nitrated petrolatum and the nitration of oxidized petrolatum

ABSTRACT: A possibility is considered of such an irreversible transformation of
realization of a random process with zero mathematical expectation which would
augment the information content of a finite-dimensional sample retaining the latter's
volume. The statistics (sets of sampled values) that have the same volume as the
initial statistics act in a dual way: on one harki, they augment information content
thanks to a concealed utilization of most of the initial realization, on the other,
they reduce the Information content because of the irreversibility of transformation.
Cases are possible when the transformation augmenting the information content does
not exist. If such transformations do exist,.an optimal should be sought which while
0 ume.,
keeping the information content of the statistics constant would minimize its v 1
