摘要：

The modification of the poly (ethylene-co-vinyl acetate) (EVA) by direct esterification of its ethylene-vinyl alcohol copolymer with mercaptoacetic acid was carried out. The amount of the mercaptan group was controlled to avoid gel formation during the graft polymerization with styrene by chain transfer. The chain transfer constant (Cs) of the SH groups and graft efficiency were measured. These graft copolymers were evaluated as a blend compatibilizer.
