Summary
α,ω-p-Toluensulphonic acid ester of poly(ethyleneglycoladipate) was synthesized and used to initiate the cationic isomerization polymerization of 2-phenyl-2-oxazoline, 2-(β-N-Carbazolylethyl)-2-oxazoline and 2-(3,5-dinitrophenyl)-2-oxazoline. ABA triblock copolymers containing poly(N-benzoylethylenimine), poly [N-β(N-carbazolyl)propionyl ethyleneimine] or poly(3,5-dinitrobenzoylethylenimine) blocks (A block) and poly (ethyleneglycoladipate) blocks (B block) have been synthesized.
