摘　　要：在微波辐照的条件下 ,通过间歇无皂种子乳液聚合 ,制得聚 [苯乙烯 -甲基丙烯酸甲酯 -丙烯酸 ]复合乳液。将所得复合胶乳进行碱 /酸分段处理 ,得到具有多孔结构的乳胶粒。用透射电镜对胶粒形态进行了表征 ,研究了不饱和酸用量、碱处理初始 p H值及碱处理时间对胶粒成孔的影响。Hollow latex particles were prepared by seeded emulsion polymerization under microwave irradiation . The particles size and morphologies were characterized with TEM images using phosphotungstic acid as a staining agent. The influences of amount of unsaturated acid monomers, the initial pH value and time in the alkali treatment on the the formation of multihollow were investigated.
