分子结构对丙烯酸酯类单体接枝LLDPE影响的研究
DOI: 10.3724/SP.J.1105.2012.12093, PP. 1349-1354
Keywords: 丙烯酸酯,聚烯烃,接枝,解聚,Q-e法则
Abstract:
利用HAAKE密炼机对比研究了甲基丙烯酸缩水甘油酯(GMA)、甲基丙烯酸羟丙酯(HPMA)、甲基丙烯酸羟乙酯(HEMA)、甲基丙烯酸乙酯(EMA)、甲基丙烯酸甲酯(MMA)以及丙烯酸羟乙酯(HEA)等具有不同分子结构的丙烯酸酯类单体对线性低密度聚乙烯(LLDPE)的接枝反应.通过对不同温度下不同反应时间的产物接枝率的测定,发现丙烯酸酯类单体接枝聚烯烃过程中均存在解聚现象.开始发生解聚现象的温度,也即解聚温度(ceilingtemperature,Tc),与单体分子结构有关.讨论了位阻效应和特殊基团(如羟基等)相互作用对解聚温度的影响,并通过丙烯酸酯类单体的溶液聚合反应确认了不同丙烯酸酯类单体的解聚温度范围.讨论了添加苯乙烯(St)作为助单体对不同丙烯酸酯类单体接枝率的影响,并结合Q-e法则和竞聚率对其进行了解释.
