摘要

报道了一种结合自缩聚乙烯基聚合和异聚反应合成支链密度可调聚苯乙烯基超支化聚合物(hypps)的通用方法。该技术是基于利用双功能单体，2,2,2-(三苯乙基)苯乙烯(TPES)，其中包含可聚合和不干扰的单位。聚合物的分支密度取决于TPES浓度和聚合时间。此外，所得的聚合物被用作大干扰素，用于亲水性单体(聚乙二醇丙烯酸酯)的共聚，得到两亲性支核星型聚合物。

Synthesis of hyperbranched polymers by combination of self-condensing vinyl polymerization and iniferter process

A versatile approach for the synthesis of polystyrene based hyperbranched polymers (hyp-PS) with tunable branching densities by combination of self-condensing vinyl polymerization and iniferter processes is reported. The technique is based on the utilization of a dual functional monomer, 2,2,2-(triphenylethyl)styrene (TPES), that contains both polymerizable and iniferter units. Branching densities of the polymers are regulated depending on the TPES concentration and polymerization time. Moreover, obtained polymers are used as macroiniferter for the copolymerization of a hydrophilic monomer (poly(ethylene glycol) acrylate) to give amphiphilic branched-core star polymers.
