摘要
在聚苯乙烯(PS)基体中采用原位生成方法制备了高1, 2 -间同聚丁二烯(s PB) /PS原位共混物,并进行了差示扫描量热分析。结果表明,该共混物为部分相容体系,随着PS用量的增加,s PB的结晶温度及结晶度都随之下降。
Polystyrene(PS) composites, which were usually prepared by blending PS with elastomer,polyolefin and nanocomposites through mechanical blending, had an excellent comprehensive performance. But the dispersion of two phases were poor due to their poor miscibility. However, research of PS modified by crystallizable polymer were rarely investigated. High 1,2-syndiotactic polybutadiene( s -PB) had a comparatively high melting point(T m), hence it was difficult to be blended by mechanical methods. In this communication, PS was modified by s-PB and a new blending approach via s-PB in situ fibrillation in PS matrix was reported.
