説明

The UV spectrum of poly-p-vinyl phenethyl cinnamate showed an absorption maximum at 278nm (ε=26800) in methylene chloride and the polymer became insoluble in organic solvents by UV irradiation.<br>The rate of disappearance of the IR absorption at 1640cm-1 attributed to the trans double bonds which was regarded as the crosslinking rate was measured under various atmospheric conditions. The reciprocal of the crosslinking rate was found to beaa linear correlation with the oxygen concentration in the initial stage of the irradiation.<br>The rate of disappearance of the trans double bonds and the rate of formation of insoluble polymer increased with the addition of the sensitizers effective for the cinnamoyl photopolymer.<br>Phenethyl trans cinnamate was synthesized and irradiated in a solid state and the photochemical reaction of the trans double bonds was investigated by measuring NMR spectra.<br>It was clarified that the trans double bonds of the cinnamate were completely disappeared accompanied by photo-isomerization.
