Means for purifying and controlling the purity of N-vinylphthalimide: Means for purifying and controlling the purity of N-vinylphthalimide. Mogilevich,I. M.; Bondarenko, V. M. (Leningr. Tekhnol. Inst., Leningrad, USSR). Deposited Doc., SPSTL 829 Khp-D82, 85-8 Avail. SPSTL (Russian) 1982. DOCUMENT TYPE: Report CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 27 N-Vinylphthalimide [3485-84-5] for poly(vinylamine) prodn., prepd. by pyrolysis of N-(b-acetoxyethyl)phthalimide [5466-90-0], is purified by extn. from the reaction mixt. with CHCl3 and chromatog. on silica gel using hexane as eluent. Purity is monitored chromatog. on Silufol plates using 2:3 petroleum ether-Et2O as eluent and I vapors as developer.

Solid state polymerization of N-vinylphthalimide: Solid state polymerization of N-vinylphthalimide. Kerekes, M.; Varga, J. (Dep. Plast. Rubber, Tech. Univ. Budapest, Budapest, Hung.). Proc. Tihany Symp. Radiat. Chem., Volume Date 1976, 4, 631-40 (English) 1977. CODEN: PTSCDP. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) The g-ray-induced solid-state polymn. of 3 polymorphs of N-vinylphthalimide [3485-84-5] (I, II, and III, m. 86, 75, and 82°, resp.) showed that I had the highest polymn. rate at 30° and II had the lowest rate. Similar results were obtained at other temps., except at >60°, where II was converted to I. The activation energy, calcd. from the temp. dependence of the solid-state polymn. rate, was 5.7 ± 0.5 kcal/mol for I and 11 ± 0.5 kcal/mol for II and III. The rate of polymn. of I and II was a linear function of the dose rate. Polymn. proceeded by a free radical mechanism. ESR spectra of the irradiated monomers and kinetic plots are given.
