摘要
利用无皂种子乳液聚合法合成了以聚苯乙烯(St)为骨架、丙烯酸乙酯(EA)和甲基丙烯酸(MAA)为共聚单体的P(St-EA-MAA)共聚物乳液;乳液经碱酸分步处理法制得共聚物多孔微球。考查了MAA用量和碱酸处理温度对微球形态的影响。
P (St-EA-MAA) copolymer latex was synthesized by a half continuous non-soap seed emulsion polymerization using styrene(St) as a skeleton, ethyl acrylate ester(EA) and methyl cyrlic acid (MAA) asmonomers. Porous copolymer[ P (St-EA-MAA) ] particles were prepared from copolymer latex by alkali/acid treatment process. The study also investigates the effects of MAA amount and alkali/acid treatment temperature on porous modality.
