1 前言分散相的存在能够引起聚合物流变学的重大改变。最具代表性的一个例子是橡胶改性的热塑性塑料。已经报道过橡胶韧化的聚合物,诸如丙烯腈-丁二烯-苯乙烯共聚物,高耐冲击聚苯乙烯(HIPS),
1 Introduction The presence of dispersed phases can cause major changes in polymer rheology. One of the most representative examples is rubber-modified thermoplastics. Rubber-toughened polymers have been reported such as acrylonitrile-butadiene-styrene copolymers, high impact polystyrene (HIPS)
