采用表面引发原子转移自由基聚合（SI-ATRP）方法，以含苄基卤的单分散聚合物微球为多功能聚合物引发剂，成功地合成了多种聚合物微球。首先，通过苯乙烯（St）、二乙烯基苯（DVB）和4-乙烯基苄基氯（VBC）的沉淀聚合，合成了一系列具有可变单体比例的含苄基氯的单分散聚合物微球（P（St-DVB-VBC））。以P（St-DVB-VBC）微球为多功能聚合物引发剂，通过表面引发原子转移自由基聚合反应（ATRP）合成了多毛聚合物微球。游离聚合物的SEC分析测得的毛发长度随M/I的增加而增加。通过SEM、FT-IR和Cl含量测量表征这些毛状聚合物微球。© 2019 Wiley Periodicals，Inc.

A variety of polymer microspheres were successfully synthesized by the surface‐initiated atom transfer radical polymerization (SI‐ATRP) of monomers by using monodisperse polymer microsphere having benzyl halide moiety as a multifunctional polymeric initiator. First, a series of monodisperse polymer microsphere having benzyl chloride with variable monomer ratio (P(St‐DVB‐VBC)) were synthesized by the precipitation polymerization of styrene (St), divinylbenzene (DVB), and 4‐vinylbenzyl chloride (VBC). Next, hairy polymer microspheres were synthesized by the surface‐initiated ATRP of various monomers with P(St‐DVB‐VBC) microsphere as a multifunctional polymeric initiator. The hair length determined by the SEC analysis of free polymer was increased with the increase of M/I. These hairy polymer microspheres were characterized by SEM, FT‐IR, and Cl content measurements. © 2019 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem.2019© 2019 Wiley Periodicals, Inc.
