It was found that the effectiveness of the energy transfer is greater for peroxides containing aromatic groups than for dipropionyl ,Card 1/2 L 38700-" .ACC MR: AP6017525 peroxide. This is explained in terms of the inductive-resonance energy transfer which is facilitated by the aromatic groups. An increase in the overall energy .transfer of the dipropionyl peroxide in benzene resulting from addition of naphtoyl ;peroxides is attributed to the great stability of the excited naphthoyl peroxide ~,molecules as well as to the contribution of the aromatic groups to the energy Itroass-, I I !fer.

The radiation yields of the isomeriz, ion ,of stilbene was found tq increase with increasing concentration of the solu- Itions approximately up to 10-3 M; with :ftirther increasing concentration, the !yields reached limiting values, and remained constant within the range of con- centrations investigated (up to 0.1 M). The limiting radiation yield of the :isomerization of trana-stilbene in cyclohexane was greater than that in ben. :zene. The fact that isomerization of trans-stilbene occurs not only in ben- zene, but also in cyclohexane, which has no stable excitation levels, indi- cates that it is due substantially to interaction of stilbene with radicale formed in the radiolysis of the solvents. At stilbeae concentrations less than 10-3 x, the reaction of prima~ry free radicals with stilbene competes with-.their mutual recomb1L*jXon,. yhereas at higher otilbene concentrations, all the primary free radicals formed from the solvent cause Isonnerization of stilbeno.

The specimens included one untreated NaCl, two heat-treated crystals at 300 and 760Cp and another grown from a malt. &citation was supplied from an x-ray tube BSV-2Cu (50 kv, 10ma) through a 0.1-= thick aluminum filter at room temperature. It was found that the mechanism involved in the process of flashing is not only the general typo but also involves a complex processs including thu excitation energy transmission phase from F-cen- tars to other electron centers. It is concluded that the presence of two photo- stimulated luminescence mechanisms is connected withronaniform distribution in recombination centers and capture centers in the crystal volume.

In addition, the data confirm the electron hole mechanism of energy transport to the luminescence centers although they do not preclude the possibility of an exciton phase as the means of transfer, especially In the final stages of the investigated process. The experi-~ ments consisted of exposing specimens of KJ-T1 phosphor to x-rays and tLen observing the intensity of the optical flash after the termination of the excitation. The in- tensity of luminescence during the x-ray exposure was also recorded. The samples were T-," I UDC: 537.531 1 535.37 ACC NRt AP6018446 exposed to x-rays for 15 minutes at a temperature of 1050K. After an initial rise, I the Intensity was observed to level off. A spontaneous optical flash followed a short! time after the termination of excitation. The temperature of the specimen was then increased to 1331K. The Intensity of luminescence was considerably higher during the subsequent irradiation, though it fell off rapidly to the level prior to the tempera- ture rise. The Intensity of the optical flash following the second x-ray exposure was somewhat higher. The temperature of the sample was increased to 1330K again. An ' at the x-ray pulse generated a luminescence pulse of an intensity comparable to that onset of the seco d excitation cycle.

The specimens# which emit a blue glowi were excited for 20-100 min with x rays from a BSV-214o tube (10 mA, 45 kV) at room temperature. The stimulating illumination was separated by means of a M-2 monochromatorp and the light source was a 400 W tung- sten lamp. The stimulation spectrum of blue radiation, measured in the 520-1100 nm range,showed a peak at X = 560 rn. Analysis of the temperature dependence of the ' brightness of photostimulated luminescence (measured with light impulses with X a 600 nm) showed this brightness to remain constant in the 239-480*K rangep and its decreas4l to be associated with a thermoluminescenco peak having = 5160K. At the latter temperature,, at which nearly one-half of the light am 1~zoratod at this peak is emitted* the brightness of the photostimulated.luminosaence decreases by a factor of 2 UDC: 539-371539'.12.o4t546.26-162 ACC NRt AP6031962 0 two. Those facts show that -photostimulated luminescence Is due to the emptying of levels (caUed, C-levels) rei~onsiblo for the high-temperature peak of thermolumines- conce. It was found also that the optical do-excitation of C-contors is associated not only with the luminescence of 415-centors, but also with the filling of levels shallower than C levels. Measurements performed by K. N. Pogodayev and V. S.

To measure the roontgenolumlnemcence the specimen was first ex- cited by 15-min Irradiation at 100P X with x-rays. The specimen temperature was then raised at tho rate of 0#28 degree/min and the specimen was periodically stimulated by 1 sec x-ray pulses. The brightness of the thermoluninescence was subtracted from the total brightness during stimulatione Measursuents, were continued up to temperatures Card 1/2 IF ACC NR, -so high that the F-flash no longer appeared, (400 to 5000 X). The results are pro- sented graphically. The temperature dependences were found to be complex and to vary considerably from specimen to specimen, but there woo a marked parallelism between the roontgonoluminesconce and F-flash temperature dependences for a given specimen. At the temporature at which the F-flash Intensity dropped rapidly and vanished, the roent genoluminescence intensity also dropped rapidly with Increasing temperature, although it did not vanish; this was the case not only In NaCl:Ni, but also in HaCl:cu, in which there is a wide temperature range between vani&hing of the F-flash and final disappearance of the r centers. The teVerature dependences of the two luminescence effects were also parallel In the specimen containing two activators, but they differs, considerably depending on whothorthoy were measured In the 630 up Cu band or the 360 m4 Ni band. An explanation of the results Is given on the basis of the hypothesis that the luminescence Is due to electron recombination at 10 activator + hold It centers, the concentration of which Is determined by the thermal dissociation of V centers* The author believes that It would be difficult to explain his results on.the bakAs of an exciton luninescome mechanism* Or1ge aft* hast 2 figUrOse SUB ODDEt 20 SM DAM ame, OR10,0 RM 006 am R~ 1 001 C.rd 2/2 SURMELI, D.D., kand. tekhn. nauk; MIKHAYLOVA, R.D., kand. tekhn. nauk; RUSYAYEVA, S.D., Inzh.; KRONGAUZ, V.N., inzb. . --'- ..

ABSTRACT: The considerable expansion of the field of application of high polymers during recent years required further investi- gation of the behavior of these p-lymers under various condit- ions, among them also in the case of their aging. This phenom- anon may be caused by various external circumstances, the caus- es may be of a physical or of Ft cher.1ical nature, Because of the immense variety of the aging-phonomona of polymers the authors considered it useful to investigate one of the simplest caus.. as of the aging of these polymers -the thermal cause- especi- ally carefully. As test object the authors selected polyhexa- methylenadipinamide. The influence exerted by the heating of the molten polyamide upon its molecular weight was especially Card 1/3 thorouChly investigated. In the case of isothermal heating From 'the Field of Heterogeneoua Chain Polyanidea, Information 62-2-15/28 'It On the Thermal Destruction of Polyhexamethylenadipina7iide. a succeasive reduction of the molecular weiGht could be ob- served, where its very definite significance was determined at 3000^.-90000 (see fig-jre 3). The processes of the growing of the chain take place simultaneously with the thermal de- struction of the polyanide in the inner medium. As the de- crease in the molecular weight takes place independent from the type of end-groupa of the chain (and still more intensively in the high-molecular polyamide), it is concluded that the de- struction-proceeoes do not only take place at the ends but aXso at anv places of the chain (fiE~ures 6-8). The experiment showed that a certain molecular weiEht in the molten poly- amide of the above-described type (independent from the init- ial stage of polymerization) a certain molecular weight is ob- tained the quantity of which depends on the temperature of the heated polyamide. The special part played by the destructive- -recombined equilibrium was emphasized in this connection, es- pecially the part of the interchain-exchange reactions in the determination of the equilibrium value of the molecular weight of the polyamide on the given conditions.

Vol 27, Nr 9, pp 1056-1083 (USSR) ABSTRACTt In the beFinning the authora noint out that in the course of the last decades the Interest of chemiEte has been directed to the investigation of the polymerization of unsaturated hydrocarbons (and their derivativen), This was mainly because Important products had to be produced for national economies. The production of various polymers is discussed, beginning with the production of new stereoregular polymers of the a- olefines by Shilldknekht and Natt. In the USSR the production of stereoregular polymers was initiated by the publications of Topchiyev and Krentsell (Refs 3,4). The different polymeriza- tion reactions, especially the aterpospecific ones, are dis- cussed (Refs 28-56). In the next chapter the authors deal with the mechanism and the kinetics of the atereospecific polymeri- zation (Refs 37,39)- In this special chapter the Isotactic polypropylene is discussed. In industrial practice those plas- Card 1/2 tics are of especial interest which are mide of products es- SOV/74-27-9-2/5 Brief Survey of the Publications on Isotactic Polymers pecially rich in icotactic polymers. Recently the qo-called fractionation method has been employed (to produce pure iso- tactic polymers); this has been done by direct polymerization (Refs 44-46). The authors then deal in dptall with the block polymers Olefs 44-49) as well as with the stereolsomeric poly- mers of diolefines (Refs 20,44,50-54). The polyvinyl chloride produced by means of' radical polymerization, the isotactic polybutene, and ia0taCtiC D01YBtyrene are then discussed brief- ly. The synthesis and the properties of well crybtallized a- olefinea with ramified chain are dealt with in a Rpecial chap- ter. Finally the authors discuss the polymer4zation of acety- lene, and the copolymers of the a-olefiner (Ref's 61,62,64). There are 20 figures, 12 tables, and 64 referf-nees, 12 of which are Soviet.

(Moscow) TITIEt New Data on Polymers MIODICAL: Priroda, 1960, No. 11, pp. 102 - 104 TEXT: The article compares methods of radical polymerization to produce atactic polyniel-s and catalytic polymerization giving isotactic or syndiotactic polymers. The hypothesis is advanced that the catalyst must contain some solid orientating surface for alignment of the radical groups in the isotactic poly- mers, since soluble or highly dispersed catalysts usually resulted in a non-iso- tactic polymer. Final proof of the hypothesis Is so far lacking. Subsequently it was found that Isotactic polymers could be produced by stereospecific polym- erization with other catalysts, e.g., 6-valent chromium compounds on alumosill- cate or borium trichlorate. By varying the conditions of synthesis, polymers of various molecular weights and properties (elasticity and strength) could be pro- duced. Stereospecific polymerization can produce unsaturated compounds with a structure similar to gutta percha or natural rubber. Prospects are good for the synthesis of olefine copolymers from ethylene or propylene by the new method. %Card 1/2 88908 New Data on Polymers S/026/60/000/011/005/009 A166/A026 These would have good chemical stability and enhanced resistance to ageing.

Compounds 11 and III could not be produced according to Claisen. By reacting 1, 11, and III with acetates of bivalent metals, the authors obtained the compounds given in the Table. In this, they made the following observationst The solubility of the polymer depends on the ionic radius of the metal which forms the polymer chain. It was found that introduction of the groups -CH 2CH 2-1 Card 3/8 S1191D)MoO3100810091019 Study in the field of coordination-...

The films produced at 200 - 3000C and 50 atm were brittle. The thermomechanical curves and the X-ray picture of the beryllium compounds of II confirmed the crystal structure of the polymers.

The melting point of III was 108-109.5 0C (Yield 20-22%). The metal polymers of the bis-(P-diketones) produced were prepared by 3-hr heating in a vacuum of 2-4 mm Hg of their equimolecular mixture with thej Card 1/4 f8176 S/190J61/003/010/004/019 Studies in the field of coordination B130/B110 0 respective Me-acetyl acetonate at 150-210 C until no acetyl acetone was set free, To remove the remaining aoetyl acetone, the resulting product was treated wifh hot water, boiled in alcohol, washed with ether, an4 dried to constant weights The copper derivatives were obtained by reaction of the diketones with copper acetate in an alcohol solution. It was found that I with Be-, Ni-, Co-. and Zn-acetyl acetonates formed nonfusible powders which were unsoluble in ordinary organic solvents and had a high decomposition temperature. I formed no coordination compounds with In and Cd. The chemical analysis showed that the composition of the resulting metal compounds corresponded to the theoretical values~ Also the metallic derJ,atives of II and III constituted colored powders. The Be-derivatives of III, and ths Be-, Zn-, and Cd-derivatives of II, are soluble in chloroform, tetrachloro ethane, dioxanei bromo benzene, and dimethyl formamide, the Ni- and Co-derivatives only in dimethyl formamide and dioxane. The peculiarities of these compounds are explained according to Hammond, Borduin) and Guter (see below)., In the interaction between tetraaoetyl ethane and the metal ions, a coordination binding of the metal takes place between the keto groups of adjacent molecules of the Card 2/4 2 8176 S/190/61/003/010/004/019 Studies in the field of coordination ...
