Abstract
The copolymerization of N-phenylethylenimine and β-propiolactone was carried out at 0°C in an acetonitrile solution. N-Phenylethylenimine and β-propiolactone copolymerized without any catalyst to give a powdery or a resinous polymer. From the results of a study of the infrared spectrum, X-ray diffraction, differential thermal analysis, and hydrolyses of the copolymer, it was concluded that the homopolymerization of neither monomer took place, and that the copolymer contained the ester structure of (Remark: Graphics omitted.)-in the main chain. The monomer reactivity ratios of N-phenylethylenimine (r1) and β-propiolactone (r2) were estimated to be r1=7.5 and r2=0.15.This publication has 2 references indexed in Scilit:
