以过氧化苯甲酰(BPO)为引发剂,聚乙烯醇(PVA)为分散剂,采用悬浮聚合方法合成了反应型增容剂甲基丙烯酸甲酯-丙烯酸乙酯-甲基丙烯酸缩水甘油酯三元共聚物(MMA-EA-GMA),研究了聚合温度、聚合时间、引发剂用量、分散剂用量及GMA含量对产物收率的影响。最佳反应条件为:反应温度70—80℃、反应时间7 h、BPO用量1.2%、PVA用量1.2%、GMA质量百分含量低于12%。 Using benzoyl peroxide (BPO) as initiator and polyvinyl alcohol (PVA) as dispersant, the reactive compatibilizer methyl methacrylate-ethyl acrylate-glycidyl methacrylate Terpolymer (MMA-EA-GMA). The effects of polymerization temperature, polymerization time, initiator amount, dispersant dosage and GMA content on the yield of the product were studied. The optimal reaction conditions were as follows: the reaction temperature was 70-80 ℃, the reaction time was 7 h, the amount of BPO was 1.2%, the amount of PVA was 1.2% and the mass percentage of GMA was less than 12%.
