J. Kriz et R. Puffr, NMR-STUDY OF THE STRUCTURE OF POLY (N-BENZOYL-8-OCTANELACTAM), Journal of polymer science. Part B, Polymer physics, 31(7), 1993, pp. 789-794
The structure of a polymer prepared by the polymerization of N-benzoyl
-8-octanelactam initiated with benzoic acid was studied by H-1 and C-1
3 NMR, using S-INEPT, COSY, COLOC, and ROESY methods, with the aid of
model oligomers. Beside the expected N-benzoylated segments, the polym
er also contained deacylated segments and about 50% of branching units
. The polymer can be characterized as a statistical, highly branched c
opolymer of N-benzoyl-8-octanelactam and 8-octanelactam.
