HYDROXYL-CONTAINING ORGANOTIN CATALYSTS FOR MAKING POLYURETHANES |
摘要 |
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 R2Sn[X-R<1>-OH]2 I <CHEM> R2Sn[O2C(Y')nCO2-Z-OH]2 III where R is a C1-C8 alkyl or an aryl group; R<1> is a C2-C22 divalent hydrocarbyl group which may contain a hydroxyl substituent; X is a linking group which may be -O-, -S- or -O2C-; 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 HSCH2CH(OH)CH2XH, preferably in a 1:0.5-1 molar ratio, where X is -S- or -O-. |
