The present invention relates to a method for producing a porous resin particle having a functional group X, the method including: dissolving a radical polymerizable aromatic monovinyl monomer and a radical polymerizable aromatic divinyl monomer together with a polymerization initiator in an organic solvent to prepare a monomer solution, dispersing the monomer solution in water in the presence of a dispersion stabilizer to obtain a suspension polymerization reaction mixture, and performing a suspension copolymerization while adding, when 0 to 80% of the entire polymerization time of the suspension copolymerization is passed, a mercapto compound represented by the formula (I):
HS-R-X (I)
in which R represents an alkylene group having a carbon number of 2 to 12, and the functional group X represents a functional group selected from a hydroxy group and a primary amino group, to the suspension polymerization reaction mixture; and the porous resin particle obtained by the method.
本发明涉及一种生产具有官能团 X 的多孔树脂颗粒的方法,该方法包括:将可自由基聚合的芳香族单乙烯基单体和可自由基聚合的芳香族二乙烯基单体与聚合引发剂一起溶解在有机溶剂中,制备单体溶液;在有分散稳定剂存在的情况下,将单体溶液分散在水中,得到悬浮聚合反应混合物;进行悬浮共聚,同时在悬浮共聚整个聚合时间的 0 至 80% 时,加入由式 (I) 表示的巯基化合物:
HS-R-X (I)
其中 R 代表碳数为 2 至 12 的亚烷基,官能团 X 代表选自羟基和伯氨基的官能团;以及通过该方法获得的多孔 树脂颗粒。
