通过β－乙硫乙基环氧丙基醚与一缩二乙二醇双环氧丙基醚开环共聚，合成了网状结构单元中具有硫醚侧基的网状聚合物冠醚，或交联大环聚醚。这类聚合物与铂金属形成的配合物，是烯烃与三乙氧基硅烷硅氢加成反应的高活性催化剂。
Through the ring-opening copolymerization of β-ethylthioethyl glycidyl ether and diethylene glycol diglycidyl ether, a network polymer crown ether having thioether pendant groups in a network structure unit was synthesized, or Crosslinked macrocyclic polyethers. The complexes of these polymers with platinum metal are highly active catalysts for hydrosilylation of olefins with triethoxysilane.
