ABSTRACT:
A radiation curable composition is provided which includes a polyorganosiloxane containing at least two ring-opening polymerizable cyclic ether groups in the molecule and having 10 to 1,000 silicon atoms as a radiation reactive polymer; a monofunctional oxetane monomer containing in the molecule one oxetanyl group and a straight- or branched-chain alkyl group having 6 to 18 carbons as a diluent; and a cationic polymerization initiator. There is also provided a process for producing a separator by coating a surface of a substrate with the above radiation curable composition and then curing the composition by exposure to radiation. A separator obtained by the above process is also provided.
