Photodegradable plastics containing halogenated diphenyl ethanes

Photodegradable plastics containing halogenated diphenyl ethanes. Freedman, Bernard; Diamond, Martin J. (United States Dept. of Agriculture, USA). U.S. US 4011375 8 Mar 1977, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08J003-20. NCL: 526001000. APPLICATION: US 74-527400 26 Nov 1974. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Polyolefins capable of photodegrdn. are prepd. by incorporating .alpha.-halogenated arom. methyl group-contg. compds. Thus, 3 g polystyrene (I) [9003-53-6] and 0.There are some commonly used reagents with their cas registry numbers 13209-15-9 and 68-36-0 in this article.03 g triphenylbromomethane [596-43-0] were dissolved in 17 ml CHCl3 and cast into a film. The film was irradiated 66 h with a 275 W RS sunlamp to give an increase in CO absorbance units of 1.184 compared with 0.246 for a control film contg. no additive. .

Triarylmethyl methacrylate

Triarylmethyl methacrylate. Yuki, Yoichi; Noyori, Ryoji; Hayashi, Masahiko (Daicel Chemical Industries, Ltd., Japan). Eur. Pat. Appl. EP 134005 A2 13 Mar 1985, 30 pp. DESIGNATED STATES: R: BE, CH, DE, FR, GB, IT, LI, NL. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: ICM: C07C069-54. ICS: C07C067-10. APPLICATION: EP 84-109315 6 Aug 1984. PRIORITY: JP 83-150038 17 Aug 1983; JP 83-188326 11 Oct 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 23, 25 Triarylmethyl methacrylates are prepd. by treating methacrylic acid (I) [79-41-4] with a triarylmethylating agent in an inert org. solvent contg. excess amine or in the presence of an anion exchanger. Thus, 0.05 mol. Et3N [121-44-8] was added to 20 mL anhyd. ether, cooled, treated with 0.01 mol I and 0.01 mol Ph3CBr [596-43-0], and held 2.5 h to give 92.9% yield colorless, prismatic triphenylmethyl methacrylate [19302-93-3] crystals having m.p. 100-101°.
