摘要：

The stereochemical structures of poly(pentyl acrylate) (PPA) prepared by solution polymerization is studied by the combination of one and two dimensional NMR spectroscopy. The OCH2, methine, methylene, and the carbonyl carbon resonances are assigned to triad, tetrad and pentad sequences respectively. The polymerization mechanism was studied using the carbonyl and OCH2 resonances. It was found that homopolymerization followed Bernoullian statistics. The various configurational assignments in the aliphatic region were done with the help of inverse HETCOR, inverse HETCOR-TOCSY, homonuclear DQFCOSY experiments.
