Photoreversible reactions of poly(vinyl cinnamylideneacetate) and its model compound

Photochemical reactions of poly(vinyl cinnamylideneacetate) and its model compound were studied. The irradiation of these compounds with light of wavelength longer than 300 nm produced dimeric forms of cinnamylideneacetyl groups, which were effectively dissociated into the monomeric forms by the irradiation with 254 nm light.
