摘要：

The influence of UV irradiation on the keto to enol ratio of poly(ethylacrolylacetate) (PEAA) in solution was examined. The major process is photoketonization, which is rapid and reversible. The role of the polymer chain is discussed in terms of its effect on the phototransformation. It is suggested that the high rate of photoketonization may be associated with the formation of sandwich complexes between the different units.
