ABSTRACT:
Disclosed are a cycloolefin resin molded product having excellent flame retardance and a polymerizable composition used for producing such a molded-product. A polymerizable composition comprising the cycloolefin monomer, a flame retardant and a metathesis polymerization catalyst is characterized in that a monomer having a condensed ring formed of an aliphatic ring having one or more carbon-carbon double bonds and a ring with aromatic characteristics is used as the cycloolefin monomer. A molded product can be produced through bulk polymerization of this polymerizable composition.
