AMINO AND AMIDO METAL CARBOXYLATES

摘要

Amino and amido carboxylates of divalent tin, zinc, cobalt and nickel which are useful as catalysts for polyurethane formulations. Such compounds correspond to either of the formulae: wherein R1 and R2 are independently C1-C20 alkyl, C6-C20 cyclohydrocarbyl, C2-C20 hydroxyalkyl or alkoxyalkyl, or R1 and R2 together with N form a nitrogen-containing heterocyclic ring of 5 or 6 atoms; R3 is a -CH2)n group where n is an integer from 2 to 6 or a group where R4 is an alkyl, cycloalkyl or aryl group of up to 6 carbon atoms; A is wherein R5 and R6 are independently hydrogen, C1-C4 alkyl or R5 and R6 together form part of a six-member cyclohydrocarbyl ring, and M is divalent tin, zinc, cobalt or nickel.
