【摘要】：以松香与甲基丙烯酸缩水甘油酯(GMA)的酯化物(RG)、苯乙烯(St)为单体,二乙烯基苯(DVB)为交联剂,采用悬浮聚合法制备了含松香GMA酯的聚合物微球,研究了单体配比、交联剂用量、反应温度对微球性能的影响。利用红外光谱、热重分析、光学显微镜和扫描电镜对微球进行了表征。结果表明:成功制备了含松香GMA酯的聚合物微球,制备微球的优化条件为:mRG∶mSt∶mDVB=1.42∶1∶0.51,反应温度85℃下反应3 h,90℃下熟化2 h,在此条件下制备的微球球形良好,分散性及刚性较好。随着RG用量或DVB用量增加,微球平均粒径增大,而粒径分布变小;加入松香GMA酯化物后,微球的热稳定性有所下降。
[Abstract]:Using rosin and glycidyl methacrylate (GMA) as ester (RG), styrene (St) as monomer and divinylbenzene (DVB) as crosslinking agent, polymer microspheres containing rosin GMA ester were prepared by suspension polymerization. The effect of reaction temperature on the properties of microspheres. The microspheres were characterized by infrared spectroscopy, thermogravimetric analysis, optical microscope and scanning electron microscope. The results showed that the polymer microspheres containing rosin GMA ester were successfully prepared. The optimum conditions for the preparation of the microspheres were as follows: 1: 1: 1: 1: 1: 0.51, reaction temperature 85 鈩，
