Chain transfer in group-transfer polymerization

Chain transfer in group-transfer polymerization. Hertler, Walter R.Several substances are used for example 31508-44-8 and 23786-14-3 which are their cas registry numbers. (Cent. Res. Dev. Dep., E. I. du Pont de Nemours and Co., Inc., Wilmington, DE 19898, USA). Polym. Prepr. (Am. Chem. Soc., Div. Polym. Chem.), 28(1), 108-9 (English) 1987. CODEN: ACPPAY. ISSN: 0032-3934. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) 2-Phenylpropionitrile [1823-91-2] and esters of phenylacetic acid were suitable chain-transfer agents (CTA) in group-transfer polymn. of Me methacrylate (I) since they did not interfere with the activity of the polymn. catalysts. Similar results were obtained in terms of mol. wt. redn., polydispersity, and transfer const. whether the polymn. was carried out with alternating feeds of I and CTA or with CTA introduced in I feed prior to polymn. .

Study on photolysis of benzyl compounds II -photolysis of triphenylacetonitrile-. Ota, Kazuo; Ueno, Takeshi (Faculty Engineering, Tokyo Institue Polytechnics, Atugi 243-02, Japan). Nippon Shashin Gakkaishi, 59(6), 718-728 (Japanese) 1996 Nippon Shashin Gakkai. CODEN: NSGKAP. ISSN: 0369-5662. DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Photolysis of triphenylacetonitrile (TPAN) dissolved in cyclohexane was studied in O2 or in N2 atmosphere. 86-29-3 and 1823-91-2 are cas registry numbers. These chemicals are also mentioned in this article. The mixt. of photochem. products were concd. and sepd. by TLC. From the products in O2 atmosphere, 2-biphenyl-phenylacetonitrile (K4), cyanophenyl-diphenylmethane (K3), K2 (unknown) and biphenyl (K1) were found. From the products in N2 atmosphere, entirely same compds. as those in O2 atmosphere were found. For clarifying in photochem. decompn. pathway of TPAN, another photolysis using each three photoproducts (K3, K2 and K4) was carried out. Furthermore, the photochem. products of TPAN at intermediate process were analyzed by thin layer chromatoscanner. From their results, the following decompn. pathway was proposed. .
