摘要
采用1-丁基-3-甲基咪唑氟硼酸盐离子液体作为聚合反应介质,以偶氮二异丁腈(AIBN)为引发剂,丙烯酰胺(AM)为亲水单体,苯乙烯(ST)为疏水单体,合成了水溶性共聚物P(AM/ST).研究得到了适宜的反应条件:总单体在离子液体中的浓度为2mol/L,引发剂的浓度占总质量分数的2%,反应温度60℃,反应时间4h,AM与ST的物质的量比为98∶2,采用该反应条件所得到的聚合物的特性黏数为2.6.通过1HNMR,13CNMR和FIRT表征了聚合物的分子结构.
The dicopolymers AM/ST were prepared with 1-butyl-3-methyl imidazolium tetrafluoroborate ionic liquids as the reaction medium of polymerization,azobisisobutyronitrile（AIBN）as iniator,acrylamide（AM）as the hydrophilic monomer,styrene as the hydraphobic monomer.Suitable reaction conditions were obtained as follows：the total monomer concentration 2 mol/L,the iniator concentration 2%（wt）,the temperature 60 ℃,the reacting time 4 h.It was show that the intrinsic viscosity of polymerization was 2.6.The structure of polymers was characterized by 1 H NMR,13C NMR and IR.
