The synthesis by aqueous RAFT polymerization of hydrophilic narrowly dispersed imidazolium-based poly(ionic liquid)s ( typically below 1.20) is reported. Full monomer conversion is achieved within hours and high end-group fidelity of the living end groups affords the preparation of well-defined block copolymers. The resulting poly(ionic liquid) macroRAFT agents are finally exploited to polymerize 2-vinylpyridine in water and generate PIL-based nanoparticles of various morphologies (spheres, vesicles, or worms) in a one-pot surfactant-free process.
报道了通过水相可逆加成-断裂链转移（RAFT）聚合合成亲水性窄分布咪唑基聚（离子液体）（通常低于1.20）。数小时内即可实现单体完全转化，活性端基的高端基保真度使得能够制备结构明确的嵌段共聚物。最终利用所得的聚（离子液体）大分子RAFT试剂在水中聚合2-乙烯基吡啶，并在无表面活性剂的一锅法过程中生成各种形态（球形、囊泡或蠕虫状）的基于聚离子液体的纳米颗粒。
