摘要

Association between a retinoid which is vitamin A or one of its bio-convertible precursors and a polyaminated polymer chosen from (A) - (F) is new. (A) polyalkylene polyamines; alkylated polyalkylene polyamines; products of the addition of alkylcarboxylic acids, aldehydes, ketones, isocyanates, isothiocyanates, or silicones, with polyalkylene polyamines; products of the addition of alkylene oxide or alkylene polymer block polyoxides with polyalkylene polyamines; quaternised derivatives of polyalkylene polyamines; dicarboxylic acid polyalkylene polyamine copolymers; (B) polyvinylimidazoles; (C) polyvinylpyridines; (D) products of addition of (A) with 1-vinylimidazole monomers of formula (I). R = H, or 1-6C alkyl(optionally unsaturated, optionally cyclic); n = 1 - 3; (E) aminated acid based polymers with a basic lateral chain; (F) reticulated derivatives of polymers (A) - (E).
