Nonterminating Alternating Copolymerization of Ethene with Carbon Monoxide and the Synthesis of Graft Polymers with alt-Ethene—Carbon Monoxide Blocks

摘要

We have demonstrated for the first time (a) the nonterminating alternating copolymerization of C_2H_4 with CO and (b) a procedure for the synthesis of graft polymers with alt-C_2H_4-CO blocks. The only related polymer reported previously was formed by a nickel(II) sytem that is specific for diblock (polyethene)(alt-ethene—carbon monoxide) polymer. Our results show that alt-C_2H_4-CO blocks can be grafted on to any carboxy-terminated polymer.
