摘要：

The influence of UV irradiation on the keto-enol ratio of poly(acryloylacetone) (PAA) in solution was examined. The tautomeric equilibrium is strongly displaced to the keto form. Important differences in the photosensitivity of the monomeric P-diketone (acetylacetone) (AA) and PAA were established depending on the structural features. The polymeric structure of PAA is an important parameter in the process. A possible route for the formation of the keto form is discussed.
