Zwitterionic Ni(II)-catalyzed carbonylative copolymerization of ethylene and cyclic ethers for the synthesis of photolytically and hydrolytically degradable polymers is reported. The segmented tetrapolymer products are composed of polyketone segments from alternating enchainments of CO and ethylene and poly(ether-co-ester) segments from non-alternating enchainments of CO, ethylene oxide, and tetrahydrofuran. Plastic and elastic products can be obtained via the general synthetic platform with the appropriate choice of catalyst and polymerization conditions.

可持续聚合物的双中心催化作用代替现有的商品聚合物-乙烯，环氧乙烷和四氢呋喃的羰基共聚

报道了两性离子Ni（II）催化的乙烯和环醚的羰基共聚，用于光解和水解可降解聚合物的合成。嵌段四聚物产物由来自CO和乙烯的交替链的聚酮链段和来自CO，环氧乙烷和四氢呋喃的非交替链的聚（醚-共酯）链段组成。通过适当的催化剂选择和聚合条件，可以通过通用的合成平台获得塑料和弹性产品。
