发明名称 Polymeric diorganotin catalysts for use in polyurethane systems
摘要 Useful as catalysts for the reaction of a polyisocyanate or a partially blocked polyisocyanate with a hydroxy-containing compound are organotin compositions obtained by reacting a diorganotin oxide of the formula R2SnO or a diorganotin dichloride of the formula R2SnCl2 with a compound of the formula HS-CH2CH(OH)CH2XH where R is a C1-C8 alkyl or an aryl group and X is -O- or -S-. Also disclosed alre cationic electrodepositable (CED) compositions containing such catalysts.
