摘要
本文采用反相微乳液聚合的方法合成了丙烯酰胺(AM)/丙烯酰氧基乙基三甲基氯化铵(AD- AMQUAT)/聚氧乙烯大单体(pEO-A)/N,N’-亚甲基双丙烯酰胺(Bis)的四元共聚物微粒。研究了该微粒助留剂的 结构与性能。这种微粒和纸纤维能够通过离子键和氢键作用显著地增强助留效果。
The PEO-grafted cationic polyacrylamide microparticles were synthesized via inverse microemulsion tetrapo-lymerization of acrylamide ( AM ) , acryloyloxyethyl trimethylanimonium chloride ( ADAMQUAT ) , PEO-macromonomer (PEO-A) and N, Af'-methylenebisacrylamide( Bis). The structure and properties of microparticle retention aids had been studied. This microparticle can connect with pulp fibre through ionic bond and hydrogen bond, which make the copolymer posses excellent retention effect.
