【摘要】 <正>绝大多数聚合物都是不相容的,直接混合很难提高它们的机械性能,因此在聚合物共混过程中需要直接加入相容剂或原位生成相容剂(原位相容)以提高产物的综合性能。反应共混的方法制备不同性能的高分子材料,使其通过共价键或离子键连接在一起,制备性能优良更多还原

【Abstract】 The effect of reactively formed graft and block copolymers on compatibilization of PS/PA6(50/50) blends has been investigated by observing morphology.Phthalic anhydride terminated polystyrene(PS-b-anh),styrene-maleic anhydride copolymer(SMA) and styrene-(3-isopropenyl-a,a-dimethylbenzyl isocyanate)(PS-co-TMI) were compared as a compatibilizer at the loadings of 1 wt%,5 wt%,10 wt%.It was found that the reactive block copolymer PS-b-anh is the most effective compatibilizer.Different reactive group of graft copolymers had little effect on the compatibilization efficiency in this polymeric blends.更多还原
