摘要
采用沉淀聚合法合成丙烯酰胺 -丙烯酸十六酯共聚物。重点讨论了合成条件如单体配比、引发剂用量、温度等对共聚反应的影响以及共聚物对苯丙乳胶的增稠性能的影响。并用DMTA和凯达尔定氮法表征了共聚物组成 ,结果表明
The precipitation copolymerization of acrylamide and hexadecyl acrylate has been carried out in DMF at 80℃ using benzoyl peroxide as initiator.The study emphasized on the relationships between the composition of copolymers and the thickening power of copolymers on emulsion.The effects of the amount of initiator,mole ratio of monomers, solvents and reaction temperature on the polymerization reaction were investigated.The copolymers were characterized by DMTA and Kjeldahl method for nitrogen determination.The experimental results show that the molecular weight of P(AM-HT) copolymers is high enough for hydrophobically associative thickening agent.
