Mechanism of growth of polymer chains during low-temperature solid-phase polymerization: Mechanism of growth of polymer chains during low-temperature solid-phase polymerization. Gerasimov, G. N.; Mikova, O. B.; Abkin, A. D. (Fiz.-Khim. Inst. im. Karpova, Moscow, USSR). Vysokomol. Soedin., Ser. A, 27(6), 1280-5 (Russian) 1985. CODEN: VYSAAF. ISSN: 0507-5475. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The quantum yields of generation and growth of chains in photoinitiated solid-state cyclopolymn. of di-Et p-phenylenediacrylate [17088-28-7] at 150-300 K were detd. The effective chain growth in the solid phase at low temps. was related to partial transformation of the energy of chem. reactions into the energy of stresses decreasing the growth barrier.

Photochemical reaction of diethyl p-phenylene diacrylate in solution: Photochemical reaction of diethyl p-phenylene diacrylate in solution. Nakanishi, Fusae; Nakanishi, Hachiro; Hasegawa, Masaki (Res. Inst. Polym. Text., Yokohama, Japan). Nippon Kagaku Kaishi, (10), 1575-8 (Japanese) 1976. CODEN: NKAKB8. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The photochem. reaction of p-C6H4(CH:CHCD2Et)2 (I) in soln. proceeded in various ways depending on the concn. of the soln., solvents, and wavelength of irradn. light. E.g., in dil. soln. (1.8 .times. 10-3 mol/), cis-trans isomerization took place, while in concd. soln. (0.72 mol/l), cyclobutane ring formation occurred. In highly concd. MeCN soln. I underwent oligomerization, giving oligomers composed of t-3,t-4-diphenyl-r-1,c-2-cyclobutanedicarboxylic acid-type cyclobutane rings. 17088-28-7 which is the cas registry number of one of substances is just one of reagents here. To clarify the reaction mechanism, UV and fluorescence spectra of dil. and concd. solns. were measured. In the latter spectra, a red shift and a flourescence peak from an excimer were obsd., which indicates that the reaction mechanism for the steroselective formation of cyclobutane ring involves an excimer. .
