An alkyl-containing porous resin with a specific surface area of 50 to 600 m2/g, the resin being prepared by polymerizing a monomer mixture of, based on the total weight of the monomers, 15 to 97% by weight of divinylbenzene, 0 to 82% by weight of at least one aromatic monovinyl monomer selected from the group consisting of styrene, methylstyrene and ethylvinylbenzene and 3 to 50% by weight of a vinylbenzyloxyalkane derivative represented by the formula
wherein n is an integer of 1 to 18, a process for its preparation and its use.
The porous resin of the invention is capable of fully exhibit its modified functions based on the variations of chemical and structural environments on the surface of resin, the functions being modified by introducing alkyl groups having varying chain lengths.
一种比表面积为 50 至 600 m2/g 的含烷基多孔塑料,该树脂是通过聚合以下单体混合物制备的:以单体总重量为基准,15 至 97% (重量百分比)的二乙烯基苯,0 至 82% (重量百分比)的至少一种选自苯乙烯、甲基苯乙烯和乙烯基苯的芳香族单乙烯基单体,以及 3 至 50% (重量百分比)的乙烯基苄氧基烷烃衍生物,其代表式为
其中 n 为 1 至 18 的整数,及其制备方法和用途。
本发明的多孔树脂能根据树脂表面化学和结构环境的变化充分显示其改性功能,这些功能是通过引入不同链长的烷基基团而改性的。
