Summary
α, ω-p-toluenesulphonic acid ester of poly(ethylene oxide) was synthesized and used to initiate the cationic isomerization polymerization of 2-(β-N-carbazolylethyl)-2-oxazoline and 2-methyl-2-oxazoline. The polymerization was carried out in bulk, and ABA type block copolymers containing poly(N-acetyl ethylenimine) or poly N-(N-earbazolyl)propionylethylenimine blocks (A block) and poly(ethylene oxide) blocks (B block) were obtained.
