Process for the preparation of colored powders of hydrolyzed ethylene-vinyl acetate copolymer

摘要

Pigment is finely dispersed in hydrolyzed ethylene-vinyl acetate copolymer by subjecting the copolymer to which pigment has previously been added by simple, non-intensive mixing to solution hydrolysis and/or by adding pigment to the solution hydrolysis medium prior to or during hydrolysis of the copolymer therein.
