用一种简便的方法制备了多种部分水解乙烯-醋酸乙烯酯共聚物(PHEVA),研究了水解度,未水解共聚物的熔体指数和酯含量对PHEVA防蜡,降凝效果的影响。
A variety of partially hydrolyzed ethylene-vinyl acetate copolymers (PHEVA) were prepared by a simple and convenient method. The effects of degree of hydrolysis, melt index of unhydrolyzed copolymer and ester content on PHEVA anti-wax and depressive effect were studied.
