Abstract
A method of deacetylation of ethylene-vinyl acetate copolymers to produce the corresponding olefinicaly unsaturated, linear polymers. The ethylene-vinyl acetate copolymers are deacetylated under a vacuum of less than about 50 Torr, by splitting acetic acid from the copolymers, and while continuously stirring the copolymers.
