Polyfunctional isocyanates free of alkali and urea groups

摘要: This invention relates to a polyfunctional isocyanate which is an acrylamide or methacrylamide homopolymer interpolymer having 20 100% of its secondary α and tertiary carbon atom amide groups converted groups, said being free alkali urea groups. The isocyanates are prepared by reacting the N-chloramide derivative polymer, in inert solvent, with amine pK value more than 7. useful for forming coating compositions.
