| abstract |
The invention provides a photocurable liquid rubber composition containing a liquid styrene-butadiene copolymer having, at each end of a molecular chain thereof, a functional group having a photocurable unsaturated hydrocarbon group, a (meth)acryloyl group-containing monomer, and a photopolymerization initiator. The composition can be used without solvent, which realizes easy control of the viscosity thereof, and which exhibits high break strength after curing. |
