摘要/Abstract

摘要： 以苯乙烯（St）为单体，丙烯酸松香与甲基丙烯酸缩水甘油酯（GMA）的酯化物（RAG）为交联剂，明胶为分散剂，偶氮二异丁腈（AIBN）为引发剂，采用悬浮聚合法制备了含羟基的松香基聚合物微球。探讨了分散剂用量、单体配比及搅拌速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等对聚合物微球进行测试表征。结果表明：成功制备了含羟基的松香基聚合物微球，微球的热稳定性、球形和分散性较好。在m_RAG∶m_St=1∶1，引发剂AIBN用量为混合单体的1%，分散剂明胶用量为混合单体的6%，搅拌速度为500r/min，85℃下反应3h，升温至90℃熟化2h时，可以制备外观最佳的微球。当固液比为0.6g/L，pH=4.5，298K吸附4h时，该微球对苯甲酸的吸附量达到172.3mg/g。

Abstract: The rosin based polymer microspheres with hydroxyl groups were prepared by suspension polymerization process that used the styrene(St)as monomer,an ester of acrylic rosin and glycial mathacrylate (RAG)as a crosslinking agent,gelatin as a dispersing agent,and azodiisobutyronitrile(AIBN)as initiator. The effects of dispersant level,monomer weight ratio,and stirring speed on the polymer microspheres were investigated. The microspheres were characterized by infrared spectroscopy(IR),thermalgravimetric analysis(TGA),optical microscopy(OM),and scanning electron microscopy(SEM). The results showed that rosin based polymer microspheres with hydroxyl groups were successfully prepared with good thermal stability,spherical shape and dispersibility. When m_RAG:m_St=1:1,AIBN of 1%(based on monomer weight,same after),gelatin of 6%,stirring speed of 500r/min,the reaction took place at 85℃ for 3h,followed by aging process at 90℃ for another 2h,the resulting microspheres were the best. The microspheres adsorbed 172.3mg/g of benzonic acid in 4h at 298K,the solid to liquid ratio 0.6g/L,and pH 4.5.
