Stabilizing polyurethane polymer compositions against light, heat and atmospheric decomposition: Stabilizing polyurethane polymer compositions against light, heat and atmospheric decomposition. Buysch, Hans J.; Oertel, Harald; Roos, Ernst (Bayer A.-G., Ger.). Ger. Offen. DE 2523107 9 Dec 1976, 33 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08K005-05. APPLICATION: DE 75-2523107 24 May 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 25 A mixt. of .alpha.,.alpha.'-bis(2-hydroxy-3,5-dimethylphenyl)-p-diisopropylbenzene (I) [34074-95-8] and .alpha.,.alpha.'-bis(2-hydroxy-3,5-dimethyl)-m-diisopropylbenzene (II) [61660-45-5] and 2 similar mixts. 7647-01-0 which is the cas registry number is also used here. of isomers were used as light and heat stabilizers for polyurethanes such as spandex fibers. The isomer mixts. were prepd. by the reaction of a mixt. of .alpha.,.alpha.'-dihydroxy-m-diisopropylbenzene [1999-85-5] and .alpha.,.alpha.'-dihydroxy-p-diisopropylbenzene [2948-46-1] with 2,4-dimethylphenol [105-67-9], o-cyclohexyl-p-cresol [1596-09-4], or 2-tert-butyl-p-cresol [2409-55-4], and high yields were obtained by satg. the phenol deriv. with HCl and adding the isomer mixt. Thus, spandex fibers contg. 2% 2:3 I-II mixt. were stable during 180 s at 180.degree. or during 340 h irradn. in a Xenotest app. .

Mixtures of: Mixtures of .alpha.,.alpha.'-bis(2-hydroxy-3,5-dialkylphenyl)-p-diisopropylbenzenes and -m-diisopropylbenzenes as polyurethane stabilizers. Buysch, Hans J.; Oertel, Harald; Roos, Ernst (Bayer A.-G., Ger.). Ger. Offen. DE 2523106 9 Dec 1976, 31 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C039-12. APPLICATION: DE 75-2523106 24 May 1975. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Treatment of a mixt. of .alpha.,.alpha.'-dihydroxy-m- and p-diisopropylbenzene with 2,4-dialkylphenols in the presence of HCl as catalyst gives high yields of mixts. of .alpha.,.alpha.'-bis(2-hydroxy-3,5-dialkylphenyl)-p-diisopropylbenzene and .alpha.,.alpha.'-bis(2-hydroxy-3,5-dialkylphenyl)-m-diisopropylbenzene, useful as stabilizers for polyurethanes. Thus, 194 g .alpha.,.alpha.'-dihydroxy-m-diisopropylbenzene [1999-85-5] and .alpha.,.alpha.'-dihydroxy-p-diisopropylbenzene [2948-46-1] in 611 g 2,4-dimethylphenol [105-67-9] was added dropwise to 611 g 2,4-dimethylphenol satd. with HCl to give .alpha.,.alpha.'-bis(2-hydroxy-3,5-dimethylphenyl)-p-diisopropylbenzene [34074-95-8] and .alpha.,. 36395-55-8 is just another one chemical used in this study.alpha.'-bis(2-hydroxy-3,5-dimethylphenyl)-m-isopropylbenzene [61660-45-5] which were effective stabilizers for polyurethanes in fiber manuf. .
