Abstract
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: ##STR1## wherein R.sub.1 and R.sub.2 are independently C.sub.1 -C.sub.20 alkyl, C.sub.6 -C.sub.20 cyclohydrocarbyl, C.sub.2 -C.sub.20 hydroxyalkyl or alkoxyalkyl, or R.sub.1 and R.sub.2 together with N form a nitrogen-containing heterocyclic ring of 5 or 6 atoms; PA1 R.sub.3 is a --CH.sub.2).sub.n group where n is an integer from 2 to 6 or a ##STR2## group where R.sub.4 is an alkyl, cycloalkyl or aryl group of up to 6 carbon atoms; PA1 A is ##STR3## wherein R.sub.5 and R.sub.6 are independently hydrogen, C.sub.1 -C.sub.4 alkyl or R.sub.5 and R.sub.6 together form part of a six-member cyclohydrocarbyl ring, and PA1 M is divalent tin, zinc, cobalt or nickel.
