摘　　要：研究了苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)单独添加和与纳米CaCO3复配添加对聚丙烯/苯乙烯-丙烯腈共聚物(PP/SAN)共混体系相容性的影响。结果表明:SBS用量为6 phr时,体系的分散性尺寸降低,分布均匀性改善,有一定的增容效果,但当其用量为10 phr时,体系的相容性变差;SBS和纳米CaCO3先在双辊塑炼机上混炼后再复配添加,当纳米CaCO3/SBS质量比为2/1、总添加量为10 phr时,增容效果好于单独添加SBS的体系;改变纳米CaCO3/SBS的配比体,系的拉伸强度和缺口冲击强度变化不大。The effects of SBS and nano-CaCO3/SBS on compatibility of PP/SAN blends were investigated respectively.The results show that when SBS content is 6 phr,the dispersion size of the blend decreases,the dispersion is more uniform;when SBS content is 10 phr,the compatibility of the blend becomes worse;when the mass ratio of nano-CaCO3/SBS is 2/1,and the total amount is 10 phr,the compatibility of the blend is better compared with the blend filled with SBS only;the tensile strength and impact strength of the blends change little with the variation of nano-CaCO3/SBS ratio.
