摘要
以双烯丙基胺和1-溴代十四烷为原料成了疏水单体N,N-双烯丙基-N-十四烷基胺(DiAC14);采取前加碱二元胶束共聚-共水解法合成了疏水缔合丙烯酰胺/丙烯酸钠/N,N-双烯丙基-N-十四烷基胺共聚物[P(AM/NaAA/DiAC14)],研究了其在水溶液中的缔合行为。结果表明P(AM/NaAA/DiAC14)缔合行为取决于其Mη的大小、疏水单体摩尔分数及其嵌段长度和分布。
Hydrophobical monomer N,N-diallyl-N-tetradecylamine(DiAC_(14)) has been synthesized via the reaction of diallyamine with 1-bromotetradecane,and then characterized.A series of hydrophobically associating water-soluble polymers poly(acrylamide/sodium acrylate/DiAC_(14)) [P(AM/NaAA/DiAC_(14))] has been prepared by co-hydrolysis with alkali before radically micellar copolymerization.The associating behaviors in aqueous solution of P(AM/NaAA/DiAC_(14)) has been examined.The experimental results showed that the properties and association behaviors were pronouncedly dependent on the M_η and the hydrophobe mole fraction,as well as the block length and the distribution of hydrophobes in the polymer chain.
