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.

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.
