METHOD FOR PREPARING POLYALKENAMERS

摘要

A method for the preparation of polyalkenamers which consists in the polymerization with ring opening of the alicyclic unsaturated compounds in the presence of a catalyst comprising three components: a) a compound of a transition metal of Groups IV-VIII of the Periodic System;b) a compound of a metal of Groups I-VI of the Periodic System; andc) quinone or its halogen derivative or an acid halide of sulfur-containing acid having the general formula RkSOnQt wherein R is halogen, aryl, alkyl, nitro- or amino-group; S can be sulfur; O represents oxygen; Q stands for halogen; k=0-1; n=1-2; t=1-2. The aforespecified component "c)" makes the catalyst more active.
