【摘要】 采用水稀释法研究丙烯酰胺(AM)反相微乳液相区,然后紫外光照引发聚合生成聚丙烯酰胺(PAM)微胶乳,再对其改性制得PAM反应性微凝胶。对产物的结构和形貌进行了表征,并探讨了其作用机理。稳定的反相微乳液外观澄清透明,离心后不分层,PAM反应性微凝胶粉末为球形或类球形,具有明显的团聚现象,颗粒粒径在200nm～400nm之间,其作为交联剂质量分数在0.9%～1.1%时,交联产物韧性较好。更多还原

【Abstract】 The water dilution xi method is used to study the range of the acrylamide reverse microemulsion,and then the UV-light polymerization is employed to synthetize polyacrylamide microlatexes,and finally,the polyacrylamide reactive microgels are successfully prepared by modifier.The structure and morphology of the polyacrylamide reactive microgels are characterized,and the mechanism are discussed.The stable acrylamide reverse microemulsion is transparent,and it will not be layered after centrifugation.The shape of the product was spherical or kind of spherical,and it had been reunited.the particle size was between 200nm-400nm.The cured product is good mechanics performance when the mass fraction of the polyacrylamide reactive microgels which are used as crosslinker are 0.9%-1.1%.更多还原
