反相乳液法制备P(AM-AA-AMPS)聚合物微球

Preparation of P(AM-AA-AMPS)polymer microspheres by inverse emulsion polymerization

以丙烯酰胺(AM)、丙烯酸(AA)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)为单体,Span-80和Tween-80作为复合乳化剂,用过硫酸铵为引发剂,通过反相乳液聚合法制备了交联P(AM-AAAMPS)微球。分别采用红外光谱仪进行结构表征,扫描电镜观察微球形貌,激光粒度分析仪分析微球粒度,光学显微镜观察微球在水中的分散性。

Cross-linking copolymer microspheres of P（AM-AA-AMPS）was prepared by inverse emulsion with acrylamide（AM）,acrylic acid（AA）,2-acrylamide-2-methyl propane sulfonic acid（AMPS）as the monomers,Span-80 and Tween-80 as compound emulsifiers,ammonium persulfate as initiator.The structure of the microspheres was characterized by infrared spectroscopy,the morphology was studied by scanning electron microscope,particle size of microspheres was analyzed by laser particle size analyzer,and dispersibility in water of the microspheres was observed by optical microscopy.
