Photopolymerizable rubber
 A photopolymerizable rubber being obtained by copolymerizing four compounds consisting of a dienic liquid rubber having hydroxyl groups, an ethylenically unsaturated monomer having hydroxyl groups, a dihydric alcohol having a molecular weight of less than 2,000 and a diisocyanate compound. The photocured product of this composition has higher tensile strength and elongation than that of the prior photopolymerizable rubbers.
