Cycloalkene terminated polyarylene ether and polyarylene ether polyalkenamer block copolymers made therefrom

摘要

Polyarylene ether-polyalkenamer copolymers are provided by effecting a ring-opening metathesis polymerization (ROMP) of a cycloalkene such as, cyclooctene in the presence of a polyarylene ether having an ester link cycloalkenyl group. An effective amount of a metallic catalyst, such as an osmium or a ruthenium halide, can be used to catalyze the metathesis.
