| 摘 要： | 研究了ＡｌＣｌ３引发的１，３－戊二烯（ＰＤ）－１－戊（ＰＩ）阳离子共聚反应。在正已烷作介质的ＰＤ阳离子聚合体系中加入ＰＩ可抑制凝胶（交联聚合物）的生成，同时使聚合物总产率下降。随共聚单体中ＰＩ含量的增加，聚合物分子量先呈现上升，并在达到极大值后逐渐下降。在甲苯介质中ＡｌＣｌ３引发的ＰＤ阳离子聚合体系中加入ＰＩ使得聚合物产率呈现下降趋势，聚合物分子量仍随共聚单体ＰＩ含量的增加先呈现上升并在达到极大值

| Abstract: | The cationic copolymerization of 1,3 pentadiene(PD) with 1 pentene(PI) initiated by aluminium chloride was carried out in n hexane and toluene. The introduction of PI in the PD polymerization system in n hexane reduces the formation of gel (crosslinked polymer) and decreases the total polymer yield. The molecular weight of the polymer increases up to a maximum with PI content in comonomer and then gradually decreases. While toluene is used as solvent, the introduction of PI reduces polymer yield. The molecular weight of the polymer increases and then gradually decreases. The results also show that while toluene is used as solvent the transfer reaction takes place between the carbocation formed by PI and toluene. |
