ABSTRACT:
Process for controlling the degree of alcoholysis of ethylene-vinyl acetate and other ethylene-vinyl ester interpolymers, by regulating the initial water content of the materials utilized to make up the reaction medium within predetermined limits in order that partially hydrolyzed polymers may be obtained having substantially constant, predetermined residual vinyl acetate or other vinyl ester contents. The partially hydrolyzed products so prepared have uniform, predetermined properties making them particularly useful in film, adhesive, fluidized bed coating, and like applications.
