摘要
首先合成苯乙烯(St)-甲基丙烯酸甲酯(MMA)共聚物种子乳液,然后进行St、MMA和甲基丙烯酸(MAA)的无皂种子乳液聚合,制得P(St-MMA-MAA)乳液。将该乳液在90℃下依次用碱和酸处理3h,经透射电子显微镜表征,证实所得共聚物乳胶粒具有多孔结构。
In this work, seed latex consisting of styrene(St) and methyl methacrylate(MMA)was first synthesized, and then copolymer latex of St-MMA-MAA(methylacrylic acid)was prepared by seeded emulsion copolymerization in the absence of soap. The obtained latex was stepwise treated by alkali and acid at 90 ℃ for 3 h,and particles with multihollow structure were observed with Transmission Electronic Microscope.
