| 摘 要： | 用悬浮接枝共聚法合成了乙烯-1-丁烯共聚物(PEB)与甲基丙烯酸甲酯(MMA)-丙烯腈(AN)的接枝共聚物(PEB-g-MAN)。用不同性质的溶剂以抽提法将接枝共聚产物所含组分逐步分离,用傅立叶变换红外光谱(FT-IR)分析了各组分聚合物的归属。研究了AN/(MMA+AN)投料质量比(fAN)对接枝共聚反应行为及产物各组分含量的影响。用凝胶渗透色谱法(GPC)对各组分相对分子质量及其分布进行了表征。结果发现,接枝共聚体系存在PEB与MMA-AN接枝共聚、PEB与MMA接枝均聚、MMA与AN共聚和MMA均聚等基元反应。

| Abstract: | PEB-g-MAN was prepared by graft copolymerization of methyl methacrylate (MMA) and acrylonitrile(AN) onto poly(ethene-co-1-butene) (PEB) with suspension polymerization. The components of the grafted copolymer were separated by different solvent and were qualitative analyzed using Fourier transform infrared spectrum(FT-IR). The effect of AN/(MMA+AN) ratio(fAN )on the monomer conversion ratio (CR),average grafting ratio (GR),grafting efficiency (GE),rubber's grafting ratio(GRR),ture grafting ratio(GRT) of copo... |
