US 5,175,201 A · Vinyl-terminated carbamylmethylated melamines, vinyl-terminated polyurethane/polyamide polymers and coating/adhesive compositions containing same

Abstract

Disclosed are novel nitrogen containing heterocyclic compounds and novel vinyl terminated polyurethane/polyamide polymers together with the use of both of these compounds in a novel adhesive and coating composition. The nitrogen containing heterocyclic compounds of the invention contain two vinyl-terminated substituents and at least one carbamylmethyl substituent and have a nucleus selected from melamine, oligomers of melamine, benzoguanamine, and oligomers of benzoguanamine, glycoluril and oligomers of glycoluril. The vinyl terminated polyurethane compounds of the invention have a molecular weight of from about 3000 to about 80000, and contain at least two vinyl end groups.
