Polymerizable composition

A method of producing a crosslinkable resin composite, comprising steps of:

• preparing a polymerizable composition comprising a cycloolefin monomer, a metathesis polymerization catalyst, a chain transfer agent, a crosslinking agent, and hollow particles;
• coating or impregnating the polymerizable composition onto or into a support medium;
• and then
• carrying out bulk polymerization of the polymerizable composition.

A method of producing a crosslinked body, comprising steps of:

• preparing a polymerizable comprising a cycloolefin monomer, a metathesis polymerization catalyst, a chain transfer agent, a crosslinking agent, and hollow particles;
• carrying out bulk polymerization of the polymerizable composition to obtain a crosslinkable resin;
• and
• crosslinking the crosslinkable resin.
