Abstract

1443797 Modifying polyvinyl alcohol EASTMAN KODAK CO 20 Sept 1973 [25 Sept 1972] 44150/73 Heading C3P [Also in Division G2] Polymers of formula wherein R is a covalent bond or an alkylene group comprising 1 to 6 carbon atoms and each R<SP>1</SP> is an aromatic radical optionally substituted with an alkyl or alkoxy group having 1 to 6 carbon atoms, are made by the reaction of a vinyl polymer containing free hydroxyl groups with an appropriate acid chloride derivative of a triarylamine. Poly - (vinyl - p - diphenylaminobenzaldehyde acetal-co-vinyl-m-bromobenzoate) is made by the reaction of polyvinyl alcohol with 4-formyltriphenylamine and then bromobenzoyl chloride. Poly-(vinyl-m-bromobenzoate - co - p - diplienylaminobenzoate) - is afforded by the reaction of polyvinyl alcohol with bromobenzoyl chloride and then diphenylaminobenzoyl chloride. Poly-(vinyl-p-diphenylaminophenyl propionate) is obtained by the reaction of polyvinyl alcohol with diphenylaminophenylpropionyl chloride. This reaction scheme can be modified by treating with bromobenzoyl chloride prior to the propionyl chloride and thus yield poly-(vinyl-m-bromobenzoate co-p-diphenylaminophenyl propionate).
