Notes:
Polymerization of 4-methyl-7-isopropyl-2-oxohexamethylèneimine (I) initiated by K ou Li was carried out at 150°C. in the presence of benzoyl chloride or the N-benzoyl derivative of I (II). The yield of the polymer was 11-25% over the course of 8-70 hr. The values of [η] in formic acid were 0.047-0.075. Optical activities of I, II, the polymers and the open chain monomer (III) were measured in formic acid.
