PHOTOPOLYMERIZABLE COMPOSITION

摘要

This invention relates to highly flexible photopolymerizable composition. This composition is composed of 10-60 wt. part of polymerizing material, 0.001-20 wt. part of photo-induced radical, 0.001-5 wt. part of thermal-polymerization inhibitor and 40-90 wt. part of preformed polymer. The polymerizing material is composed of 5.50 wt. part of acrylate and 5-50 wt. part of non-gaseous compd. containing more than 2 ethylene therminals. The preformed polymer is prepd. by polymerization of styrene, vinylchloride and ethylene carboxylate (or anhydride).
