在玻璃态脆性高聚物中引入一定体积分数的橡胶粒子能显著地提高这些高聚物的韧性,这和由橡胶粒子引发的银纹有关,苯乙烯-丙烯腈无规共聚物(AS)与AS在丁二烯橡胶上的接枝共聚物(AS-g-PBd)所组成的共混物是一种重要的共混体系。我们用透射电镜(TEM)研究了该共混体系的形态与银纹的关系。
The introduction of a certain volume fraction of rubber particles into the glassy brittle polymer can significantly increase the toughness of these polymers, which is related to the silver grain induced by the rubber particles, the styrene-acrylonitrile random copolymer (AS) The blend of AS graft copolymer on butadiene rubber (AS-g-PBd) is an important blending system. We used TEM to study the morphology of the blends and the relationship between the silver lines.
