摘要
本文根据高分子的分子设计原理 ,合成了带苯基的疏水单体N 苯基对正丁基丙烯酰胺 (BBAM )。采用自由基胶束共聚的方法制备了水溶性丙烯酰胺 N 苯基对正丁基丙烯酰胺 (BBAM)疏水缔合型共聚物 (PA BA)。研究了共聚物溶液的性能及影响因素。结果表明 ,随共聚物溶液浓度的增加 ,在临界缔合浓度以上 ,分子间缔合大量形成 ,水溶液表观粘度迅速增加 ,表现出明显的疏水缔合行为。
A hydrophobic monomer with benzyl group N arylalkylacrylamide(BBAM) was synthesized and water soluble acrylamide/N arylalkylacrylamide(BBAM) hydrophobic associating copolymer(PABA) was prepared by free radical micellar polymerization.The properties of the copolymer solution were studied in detail.Intermolecular association increased with the increasing concentration of the copolymer (above the critical concentration),and the apparent viscosity increased rapidly.The action of hydrophobic association was evident.P(AM/BBAM) show a better anti salt effect than HPAM.
