摘要: 采用自由基胶束聚合的方法合成了侧链上含有两个苯环和长链烷基的氨酯型疏水缔合水溶性聚合物,探讨了不同侧链链长的疏水聚合物及不同表面活性剂下共聚物溶液的增粘效果,当侧链上烷基碳原子数n=8及用十二烷基苯磺酸钠作表面活性剂时,共聚物具有较好的增粘性能。对聚合物的合成条件进行了研究,结果表明合成聚合物的最佳实验条件为:引发剂浓度0.2%,疏水单体摩尔用量0.5%,丙烯酰胺(AM)浓度10%~15%,表面活性剂用量0.75%。

Abstract: A hydrophobic associated water-soluble polymer with two phenyl groups and long chain alkyl in side chain has been syn- thesized in aqueous solution by radical micellar polymerization.Thickening effect of the copolymers aqueous solution with dif-ferent hydrophobic group length existing in different surfactants has been studied. Results obtained show that the copolymers
behavior excellent property of viscosity increasing when the numbers of carbon atom in hydrophobic group are 8 and dodecy-benzene sulfonic sodium exists. In addition, conditions of the synthesized reaction are optimized through orthogonal design method and the optimal reaction conditions are as follow: the concentration of acrylamide is 10%-15%, the feed of initia-
tor, hydrophobic monomer and surfactant are 0.2%, 0.5%(mol), 0.75% relative to the AM feed, respectively.

Key words: radical micellar polymerization, hydrophobic associated, synthesis
