HCID 6440878POLY(VINYL ACETATE-CO-CROTONIC ACID)

Procedure

Polymerization is terminated when the degree of polymerization reaches 85%, by the introduction of 4 ml of an aqueous solution containing 0.008 g of hydroquinone. The vinyl acetate which has not yet reacted is eliminated by distillation. The crotonic acid which has not yet reacted is eliminated by washing of the resulting beads with water.
