【摘要】 以丙烯酰胺AM、甲基丙烯酸二甲氨基乙酯氯甲烷盐DMC、聚醚分散剂等为原料,采用乳液聚合法,合成出了一系列AM-DMC阳离子共聚物乳液,测定了乳液的粘度与稳定性,找出了合成AM-DMC阳离子共聚乳液的最优配方和条件。把AM-DMC阳离子共聚乳液加到废纸浆中,测其打浆度与留着量等,当AM-DMC乳液用量为0.10%时,其助留助滤效果最好。更多还原

【Abstract】 A series cationic emulsion copolymers based on acrylamide(AM),methacrylogyloxyethl trimethylammonium chloride(DMC)and dispersant were synthesized by means of emulsion polymeriza-tion.The viscosity and stability of emulsions were determined.The optimum condition of synthesis of copolymer was discovered.This cationic copolymer emulsion was applied in paper making to deter-mine retention and beating degree,etc.The retention and drainage properties were the best when quantity of the applied emulsion was0.10%.更多还原
