Hydroxyl-containing organotin catalysts for making polyurethanes

Useful as catalysts for the reaction of a polyisocyanate or a partially blocked polyisocyanate with a hydroxyl-containing compound are hydroxyl-containing organotins such as, for example, compounds of formulas I-III STR1 where R is a C1 -C8 alkyl or an aryl group; R1 is a C2 -C22 divalent hydrocarbyl group which may contain a hydroxyl substituent; X is a linking group which may be --O--, --S-- or --O2 C--; Y is a hydroxyl-containing C3 -C5 alkylene group; Y' is a C1 -C9 divalent hydrocarbyl group; Z is divalent organic linking group; and n is 0 or 1. Suitable hydroxyl-containing organotin compounds would also include polymeric organotin compounds prepared by the reaction of a diorganotin oxide or diorganotin dichloride with HSCH2 CH(OH)CH2 XH, preferably in a 1:0.5-1 molar ratio, where X is --S-- or --O--.
