Vereshchinskly, I.V., Karpushkip, L.T. Effect of Y -Radiation on the
Synthesis of Indophenol 265
The synthesis of indophenol from an irradiated mixture of
a-naphthol and n-phenylene dismine was studied. The radiochemical
yield of indophenol is 4.7 molecules per 100 ev, and the yield of
the leuco form from the dye solution in vacuum is r,-, 1.8 molecules
per 100 ev. It was shoim that the formation of the dye Is a Wo-stage
process. The first stage Is the formation of the leuco, forms It does
not require the presence of molecular oxygen. The second at*e is the
conversion of the leuco form into the dye. This stage occurs only in
the presence of molecular oxygen. Irradiation considerably accelerates
the conversion of the leuco form. There are 9 figitres and 12 references

TITLE: Double Bonds in Polyethylene Irradiated by Fast Electrons-
PERIODICAL: Doklady Akademii nauk SSSRI 1959, Vol 12), Nr 6, pp 1347-134?,3
(USSR)
ABSTRACT: Polyethylene was irradiated in liquid nitrogen with 23-300 Mrad
and the infrared spectrum was recorded at variou3 temperatures
(Fig 1). Immediately after irradiation, an abs3rption band at
966 cm'_1 may be observed, which confirms that the double bonds 41
of the tranavinylene type are formed at the inntant of irradia-
tion by stripping off H-atoms in two adjoint methylene groups.
The intensity of the band 909 cm-1 corresponding to the intensi-
ty of the vinyl group depends in a high degree on temperature
and on the intensity of irradiation. This is explained by
reaction of the vinyl group with free radicalelfoped by ir-
radiation. Irradiation at temperatures below----100 with
206 Mrad causes the bands 985 cm- 11and 944 cm-I to occur in the
spectrum (Fig 2). The band 944 cm- vanishes again with a tem-
Card 1/2 perature rise and is probably caused by short-lived radicals.@@

TITLE:
Influence of Ionizing Radiations on the Structure of Poly-
amides
PERIODICAL: Doklady Akademii nauk SSSR. 1959, Vol 4,27, Nr 4; PP 831 - 831.
(USSR)
ABSTRACT: The effect of ionizing radiations on the structure of pol.--
amides was investigated by infrared spectroscopy in the pres-
ent paper. Caprone- and copolymeric caprone-nylon films (the
latter two components at a ratio of 1:1) were irradiated by
6o
accelerated (200 kv) electrons and by Co -t-radiation. The
experimental methods are described in the paper (Ref 1). From
a comparison of the infrared spectra of the irradiated and not
irradiated amides, it could be ascertained: (1) The irradiatiom
effects a variation in the number of methylene groups in the
methylene chain of polyamides (the band of deformation vibra-
tione of the CH 2-Croup becomes weaker, the intensity maximum
of these vibrations is shifted toward a range of longer waves).
(2) The intermolecular hydrogen bridges are broken (the bands
Card 1/3 corresponding to the valence vibrations of the NH-bond with
Influence of Ionizing Radiations on the Structure of SOT/20-1.27-4-29/60
Folyamides
enclosed intermolecular hydrogen bond become weaker). (3) Be-
sides, the destruction of the intermolecular hydrogen bond,
intramolecular hydrogen bonds are formed during irradiation.
From the stretched P--form of the polyamides, a spiral a-form
originates (maximum shift toward the range of valence vibra-
_4
tions of the carbonyl group from 1638 CM (this band corre-
sponds to the P-form) to 1650 cm- 1 (a-form). (4) In the irra-
diation (as well as in melting) the polyamidee pass over into
the amorphous phase (comparison of the spectra of irradiated
and melted polyamides). By irradiation, spiral polyamides are
formed from the stretched ones, which leads to a ring formation
and to an inner connection by intramolecular hydrogen bonds.
The figures show the individual spectral variations mentioned.
The detected conversion of the P-form o.' the polyamides into
the a-form by irradiation is, perhaps, one of the causes of
the destruction of normal living conditions of the organism.
Finally, the author thanks Academician V. A. Kargin for the
Card 2/3 discussion of the results obtained and for valuable advice.

Investigation of the Effect of Ionizing Radiations Upon the
Chemical Structure of Rubber-like Fluorine Copolymers
PERIODICAL: Vysokomolekulyarnyye soyedineniya, 1960, Vol. 2, No. 4,
pp. 485-491
TEXT: The authors proceed from published data (Refs. 1-5), according to
which, unlike what is the case with polytetrafluoroethylene and
polytrifluorochloroethylene, in the case of rubber-like copolymerslnot
destruction but structure/formation is caused by ionizing radiation
(radiation vulcanization)0)@he authors therefore investigated this
process on Mp -32 (SKF-3@ fluorine polymers. As a radiation source,
a co60 apparatus wiTE-a-F-a-Mvity of 1,400 and 21,000 gram-equivalent of
radium was used. The int nsity of irradiation was 0-54.106 r1h; the
total dose was 3 - 80-109 r. The copolymer films were irradiated in air

or vacuum (jo-4 torr). The chemical changes occurring as a result of
irradiation were examined by infrared spectroscopy. By means of an
VIKC, -14 IKS-14) spectrometer, the spectra in the range from 500 to
1450 cm-@ were taken on 44 thick films, and within the range from
1450 - 3500 cm-1 on 140 - 150p thick films. Fig. 1 shows the infrared
spectrum of the initial copolymer, which is interpreted by the authors.
Irradiation in air leads to considerable changes (Figs. 20). The
intensity of the absorption bands of oxygen-containing groups and of the
-CF=CF2 group increases considerably, while the intensity of the C-H,
C-F, C-Cl bond stretching vibrations decreases. Herefrom it is concluded
that gaseous compounds containing H, F, or C1 are liberated. Fluorine
copolymer irradiated in vacuum shows a different spectrum (Fig. 4). At
small doses (10.10� - 20-106 r), the absorption bands 1640 cm-1
(-CH=CF-); 1740 cm-'*(-CH-CF2 or R-CF=CF-R); and 1840 cm-1 occur. The
latter band is interpreted by the authors as belonging to the group
-CF=CF2. At higher doses, instead of the 1740 and 1840 cm-1 bands, a
broad band with a maximum at 1800 cm-1 occurs. This is explained by the

formation of cross links at the expense of the double bonds. The
considerably decreasing solubility with increasing radiation dose
(Fig. 5) confirms this assumption. An increased content of vinylidene-
fluoride promotes cross linking (Fjg. 6). A linear interrelation between
cross links and vinylidenefluoride'lcontent was found (Fig. 7). At the
same time, however, also destruction occurat which manifests itself by
decreasing viscosity (Fig. 8). The authors draw the conclusion that in
the fluorine copolymer the same reactions occur during irradiation as in
polyethylene: loosening of C-H bonds accompanied by the formation of free
radicals and free hydrogen atoms, which either form compounds with
neighboring H, F, or Cl atoms under the formation of double bonds and E29
HF, or HC1, or take such atoms away fron another polymer chain under the
formation of a further free radicaltj The recombination of the free V@
radicals leads to cross linking. h increasing copolymer content, the
number of double bonds increases. There are 6 figures and 8 references:
5 Soviet, 1 US, 1 French, and 1 British.

quantities of calcium oxide was found to increase polymer strength* The
change in strength after irradiation of polymers containing varying
amounts of calcium oxide is shown graphically in Fig. 1. The viscosity
of methyl-ethyl ketone solutions of the polymers decreases after ir-
radiation. The infrared spectra of fluorinated polymers type CO -32
(SKF-32) before and after irradiation, with and without calcium oxide, are
shown in Figs- 5,6# and 7. A considerable number of conjugate double bonds
of the type -CH=CCl-, and OH and HP- groups were found to form in the
2
presence of metal oxides. Metal oxides prevent the formation of volatile
compounds during irradiation, since they react with these compounds*
Calcium and magnesium oxide bind volatile compounds which form on heating
fluorinated polymers to 2000C under pressure. The infrared spectra of
fluorinated polymers before and after heating under pressure to 2000C,
with and without admixture of calcium oxide are given in Fig. B. In the
irradiation of fluorinated polymers, the metal oxides act as acceptors
for hydrogen-fluoride and hydrogen-chloride compounds and for fluorine,
chlorine, and hydrogen. There are 8 figures, 1 table, and 11 referencest

TITLE: Infra-red spectra of some derivatives of unsaturated
phosphinic acids
PERIODICAL: Izvestiya Akademil nauk SSSR. Otdelenlye khimicheskikh nauk,
no. 1, 1961, 71-76
TEXT: The pwpose of the present paper was to verify the structural
formulas of various previously (Ref.1)synthesized derivatives of unsaturat-
ed phosphinic acids based on their infra-red spectra, as well as to study
the mutual influence of atoms and groups inside their molecules. The
spectra were taken by means of a Hilger ,rA-209 (D-209) infra-red spectro-
meter. A table indicates those absorption bands from which conclusions
were drawn as to thestructure of the analyzed substances. In detail, the
following has been found: The chlorine atom bound to the C-atom neigh-
boring the C=C bond (ester II) increases the frequency of stretching
vibrations of the C-C bond. The absorption bands 870-910 cM'1 correspond-

ing to deformation vibrations of the CH group at the C-C bond confirm the
existence of vinyl groups in IV and of vinylidene groups in I, II, III.
The shift of these bands In I! is also attributed to the neighboring
chlorine atom. In relation to IV where the phosphorus group is not
conjugated with the CaC group, frequency in V is reduced by 40 cm-1. Since,
however, the P-0 group, due to its different configuration, cannot be
located in the same plane as the C-C group, 'this effect is attributed to
the phosphorus atom. In the esters VII to IX, a similarity with the
spectra of pentadiene and isoprene was found in the range
1
1640-1585 cm- , which is attributed to the corresponding bands of
symmetrical and antisymmetrical vibrations of the conjugate double bonds.
The band shift is attributed to the neighboring phosphorus1atom. All
compounds show intensive bands in the range 1250-1270 cm- ; these bands
correspond to the P-Obond,andin the case of acid chlorides, they are shifted
by 20 cm-1 toward higher frequencies, owing to 'UhV action of the chlorine
atoms. The intensive doublet bands 1060-1000 cm-' are attributed to
vibrations of the 0--C bond In the P-0-C groups. There are 3 figures,
1 table, and 10 references: I Soviet-bloc and 8 non-Soviet-bloc.

TEXT: By means of spectroscopic studies the authors attempted itoelf! &in @Le
character of the structural changes in polystyrene on irradiation with fast
electrons. The polystyrene films were irradiated in the vacuum (jo-4 mm Hg)
at room temperature in a 200 kv electron accelerator tube. The electron
spectra and the infrared spectra were taken by means of anC@_4 (SF-4) spec-
trometer and anH-800 (N-800) spectrophotometer, respectively. The authors
studied 'specimens of amorphous polystyrene W with a molecular weight of
600,000 and 1,300,000, and isotactic crystalline polystyrene (II). To re-
move the monomeric and low-molecular fractions, polystyrene was precipitated
several times from a toluene solution by means of methyl alcohol. For the
complete removal of the solvent the films were dried in high vacuum. The
infrared spectrum of non-irradiated (II) essentially differs from that of
non-irradiated (I). After the irradiation of (II) changes are observed in

562 cm- is shifted towards lower frequencies; besides, the intensity is re-
duced. Amorphization of isotactic polystyrene on irradiation ' .1 f
dfs'_tinct4@y appears at the point where the 917 cm-1 band is shitte*d. On
irradiation of polystyrene with doses higher than 2500 Mrad the contour of
the spectrum strongly changes at the highly intense 700 cm-1 band and at the
weak 840 cm 1 band. This indicates that double bonds of the type R2C - CER
and cis-RCH - RHC are formed in the polymer. Hence, the process of cross-
linking can be explained by the scheme of L. A. Wall and D. W. Brown (see
below). According to this scheme the hydrogen released by the rupture of
the CH bond of the main chain hydrogenates the neighboring ring of the
phenyl molecule under formation of a cyclohexadiene ring with double bonds
and cross-linking of the neighboring molecules. Conjugate systems with
double bonds are formed in the main chain of polystyrene. Ye. 1. Pokrovskiy
and M. V. Vollkenshteyn are mentioned. There are 5 figures, 1 table, and
12 references: 5 Soviet-bloc and 7 non-Soviet-bloc. The 3 references to
English lanCuage publications read as follows: L. A. Wall, D. W. Brown,
