A Polymer by Anionic Polymerization of epsilon-Caprolactam with the Presence of Polycarbonate,and its Characterization

摘要

The anionic polymerization and copolymerization of epsilon-caprolactam has been studied for many years [1,2].The advantages of using an anionic method are:fast kinetics,high monomer conversion and little side-product [3].Research being done includes:polymerizing epsilon-caprolactam using various activators and initiators[4-6];block copolymerization of epsilon-caprolactam by making chain-growth at the end of a second polymer blcok[7-10];blend with a second polymer by first dissolving the second polymer into monomer and then polymerizing epsilon-caprolactam [11] etc.
