Abstract:
1. A process for producing an interpenetrating polymer network structure, which comprises the steps of impregnating a polymer molding with a radical polymerizable composition containing an ethylenically unsaturated compound and a radical polymerization initiator; and polymerizing the ethylenically unsaturated compound in a swollen state of the polymer molding impregnated with the radical polymerizable composition; wherein a chain transfer agent is added to the radical polymerizable composition and/or the polymer molding before impregnating the polymer molding with the radical polymerizable composition, and the chain transfer agent is at least one kind of a compound selected from mercaptan having an alkyl group having 3 to 12 carbon atoms and an aromatic hydrocarbon-based chain transfer agent.
