Polymers stabilized by esters of phosphinodithiolic acids: Polymers stabilized by esters of phosphinodithiolic acids. Stretanski, Joseph Anthony; Grosso, Vincent Gerard (American Cyanamid Co., USA). U.S. US 4064106 20 Dec 1977, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08K005-50. NCL: 260045950C. APPLICATION: US 75-635184 25 Nov 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Phosphinodithioate esters (I, R,R' = optionally substituted alkyl, cycloalkyl; n = 1,2; when n = 1, R2 = optionally substituted alkyl, cycloalkyl; when n = 2, R2 = alkylene, hydroxyalkylene, thiobis(alkylene), arylene, optionally substituted) are efficient light stabilizers for polymers, e.g. polypropylene (II) [9003-07-0]. Thus, 14.0 g dicyclohexylphosphinodithioic acid [2512-58-5] and 16.67 g octadecylbromide [112-89-0] were refluxed 15 h in 250 mL Me2CO to give octadecyl dicyclohexylphosphinodithioate (III) [65728-04-3]. When a test sample of II contg. 0.5% III was exposed in a Weather-O-Meter, it lasted 600 h longer than the control.

Piperidine derivatives as light stabilizers for organic materials: Piperidine derivatives as light stabilizers for organic materials. Rasberger, Michael; Rody, Jean (Ciba-Geigy A.-G., Switz.). Ger. Offen. DE 2719133 1 Dec 1977, 27 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07D213-78. PRIORITY: CH 76-5892 11 May 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 27 Piperidine deriv. (I) [65402-63-3] and 2 similar esters prepd. from 4-carboxy-4-hydroxy-2,2,6,6-tetramethylpiperidine [65402-65-5] and Br(CH2)7Me [111-83-1], Br(CH2)17Me [112-89-0], or Br(CH2)4Br [110-52-1] were useful for light stabilizers, e. 65402-63-3 which is the cas registry number of some chemical is mentioned.g., for polypropylene (II) [9003-07-0]. Thus, II contg. 0.2% phenolic antioxidant and 0.25% I was stable for 5760 h in UV light, compared with 1050 h without I. 65402-63-3 is also in the experiment. ..
