单体N,N-双烯丙基十二胺的合成及其疏水缔合水溶性聚合物的性能

以双烯丙基胺和1-溴代十二烷为原料合成了疏水单体N,N-双烯丙基十二胺(DiAC12),采用前加碱二元单体胶束共聚-后水解法制备三元共聚物丙烯酰胺/丙烯酸钠/N,N-双烯丙基十二胺P(AM/NaAA/DiAC12)],以芘为荧光探针,利用荧光光谱研究了P(AM/NaAA/DiAC12)在水溶液、1.000 mol/L NaCl水溶液中的缔合行为。结果表明,当疏水单元摩尔分数x(DiAC12)=0.10%～0.40%时,随聚合物浓度、疏水单体用量的增加,芘的I1/I3值减少,缔合作用增加。

Synthesis and properties of hydrophobically associating water-soluble polymers P(AM/NaAA/DiAC_(12))

Hydrophobical monomer N,N-diallyl-N-dodecylamine(DiAC12) had been synthesized by the reaction of diallyamine with 1-bromododecane.The terpolymer P(AM/NaAA/DiAC12)] was prepared by hydrolysis with alkali before radically micellar copolymerization.The associating behaviors of P(AM/NaAA/DiAC12) in aqueous solution and 1.000 mol/L NaCl solution had been examined by fluorescence spectrum as probe with pyrene.It was observed that when hydrophobic molar fraction were 0.10%～0.40%,with the increase of polymer concentration and hodrophobe molar fraction,the I1/I3 values of pyrene decreased,the associating action had increased.
