BA/MMA高吸油树脂的合成与性能研究

A Study on the Synthesis and Properties of Butyl Acrylate/Methyl Methacrylate High Oil Absorption Copolymers

以丙烯酸丁酯(BA)和甲基丙烯酸甲酯(MMA)为单体,过氧苯甲酰(BPO)为引发剂,N,N-亚甲基双丙烯酰胺为交联剂,采用溶液聚合法制得丙烯酸丁酯与甲基丙烯酸甲酯共聚吸油性树脂。正交实验结果表明最佳合成条件:mBA:mMMA=3:1,交联剂1%,引发剂1%,温度85℃。此条件下制得的树脂吸油倍率21 g.g-1。

Solution copolymerization of butyl acrylate （BA） and methyl methacrylate （MMA） is studied by using N, N- methylene bisacrymide as the cross linking agent and benzoyl pemxide（BPO） as the initiator. The optimum conditions from orthogonal experiment are as follows： mBA： mMMA = 3：1, wt（cmss linking agent） = 1% ,wt（initiator） = 1%, temperature = 85 ℃. The oil absorption power is 21 g· g- 1 for toluene.
