摘要：

The structure of end groups in Poly(vinyl alcohol) was investigated by **1H-NMR spectroscopy. Among various kinds of end groups formed by chain transfer reactions to monomer and polymer, one of the end groups was found to exist in the gamma -lactone form under acidic condition, while in the carboxylic acid sodium salt form under the alkaline condition. No free carboxylic acid group was detected.
