摘要

本文为提高苯乙烯-丁二烯-苯乙烯嵌段共聚物（Styrene-Butadiene-Styrene triblock copolymer，SBS）与尼龙6（PA6）共混物的相容性，利用SBS的辐射交联对其进行辐射改性，赋予共混物更好的性能。SBS在常温空气气氛下,60,Co γ 射线辐照至一定剂量发生化学交联，在共混物内形成三维网络结构，使两相间产生强制互容作用。对改性前后共混物微观形貌，流变性能，机械性能及吸水性的分析与表征。结果表明，辐射交联改性增容后SBS/PA6聚合物合金的性能得到明显提高。

Abstract

This work is aimed at improving compatibility of styrene-butadiene-styrene (SBS) copolymer / polyamide 6 (PA6) blends through radiation crosslinking of the blends by ,60,Co γ-rays, in which three-dimensional network structure is formed by the crosslinked SBS molecular chains. Micro-morphology, rheological properties, mechanical properties and water absorption of the PA6 / SBS blend with different ratios irradiated to 100 kGy were characterized by relevant instrumental techniques. The results show that performance of the SBS/PA6 blends could be improved by radiation modification of the SBS copolymer.
