P(St-EAE-MAA)共聚物多孔微球的合成

Synthesis of Porous Copolymer[P(St-EA-MAA)] Particles

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.
