摘要
以丙烯酸酯类为主要单体通过乳液聚合方法合成阳离子聚合物乳液。分析了聚合工艺、乳化剂、引发剂、功能性单体、单体种类及软硬单体配比等因素对乳液性能的影响。研究结果表明:采用微乳液聚合工艺,阳离子乳化剂采用31527,用量为单体总质量的5%,阳离子乳化剂:非离子乳化剂=4:1(质量比),阳离子引发剂用量为单体质量的0.5%,硬单体为MMA,功能性单体采用NMAM时乳液具有较好的综合性能。
This paper based on acrylic ester as the main monomer synthesized the cationic polymer emulsion by emulsion polymerization methods.The effect of emulsifier,initiator,the polymerization process of emulsion,and the change of the kind of functional monomer and reactive monomer on cationic polymer emulsion are explored.The results indicate,when cationic emulsifier adopts 31527,the amount of emulsifier is 5% of the total mass of monomer,the micro-emulsion polymerization is used,cationic emulsifier： non-ionic emulsifier=4：1（mass ratio）,the dosage of cationic initiator is 0.5%,the monomer can well copolymerize and the properties of emulsion are better.
