摘　　要：由丙烯酰胺和三甲基烯丙基氯化铵合成了阳离子型共聚物，对合成配方及合成反应条件进行了考察，按最佳配方和最佳反应条件制得的共聚物在室内性能评价中显示了良好的防粘土膨胀、抗温、抗盐等性能。The optimum composition of reaction mixture and reaction temperature and time in aqueous solution copolymerization of acrylamide,AM,with trimethylmonoallylammonium chloride.TMAAC,are investigated and established.A cationic copolymer AM/TMAAC,or AT with [η](in water at 30℃)=101.4 ml/g and cationization degree C=20.32% is obtained.This copolymer AT has high anti-clay-swelling ability,the linear dilation rate of clay sample in 500 ppm AT solution being decreased by 54.0% as compared with that in water.It is heat resistant(up at least to 80℃) and tolerent to salts,viscosity reduction in 25% CaCl2+MgCl2+NaCl(in3:2:3)solution being 5.3%.
