Tertiary amino acid and tertiary amino acid-nitrile delayed action catalyst compositions

Claim 1

In a process for polymerizing a urethane forming composition comprising an organic polyisocyanate and a polyol, in the presence of an organometallic catalyst, the improvement which comprises including as a catalyst component an amino catalyst selected from the group consisting of a polyfunctional amino acid and an amine salt of a polyfunctional amino acid as represented by the formula: ##STR4## wherein R 1 and R 2 are hydrogen atoms with only one being hydrogen at a time, alkyl and substituted alkyl groups having from 1 to 15 carbon atoms, or combined to form a piperidine, piperizine, morpholine, imidazole or imidazoline radical; wherein R 3 and R 4 are alkylene groups having from 1 to 2 atoms, aralkylene with the alkylene portion having from 2 to 6 carbons, substituted alkylene and substituted aralkylene; wherein R 5 is hydrogen, a lower alkyl group having from 1 to 6 carbon atoms, an alkenyl group having from 1 to 6 carbon atoms, an aryl group, a cyclic group and substituted derivatives thereof, or a keto alkyl group with the alkyl portion having from 1 to 6 carbon atoms; wherein R 6 is hydrogen, or a radical selected from the group consisting of alkyl, phenyl, furfuryl, naphthyl, and substituted derivatives of such groups; wherein X is a carboxylic acid group or a quaternary ammonium salt of an acid group; wherein Y is a carboxylic acid group, nitrile group, or a quaternary ammonium salt of an acid group; and wherein m, n and s independently are 0 or 1; wherein q is 0 or 1; wherein p independently is 1 or 2; and wherein p + q + s is 3.
