Abstract
An alkali- and urea group-free polyfunctional isocyanate derivative of a homo- or co-polymer of acrylamide or methacrylamide is prepared by reacting a corresponding N-chloroamide derivative of the homo- or co-polymer of acrylamide or methacrylamide with a tertiary amine having a pKa value of more than 7 in the presence of an inert solvent and at a temperature of from 20 to 180 DEG C. The derivatives may be used in coating compositions.
