Carboxy end-capped polybutadine and butadine-acrylonitrile copolymer were transformed into dicationically living poly (THF-b-butadine-b-THF) and poly (THF-butadine-avryloni-trile-b-THF) triblock chains
respectively
through the ring-opening polymerization of THF. By terminating the reaction with liquid ammonia or diethylamine the telechelic triblock with primary or tertiarr amine end-groups
respectively
was synthesized. The tertiary amine terminated triblock oligomer reacted with a
a'-dic
hloro-p-xylene gives rise to the formation of thermo-plastic elastomer ionene polymer.
