采用巯基乙酸对乙烯-乙烯醇共聚物（伊娃）进行直接酯化改性。通过链转移反应控制了接枝基团的量，避免了苯乙烯接枝聚合过程中凝胶的形成。测定了SH基团的链转移常数（Cs）和接枝效率。这些接枝共聚物作为共混物增容剂进行了评价。John Wiley & Sons，Inc.
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. © 1993 John Wiley & Sons, Inc.
