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.
Claims2
A method for preparing a polymerizable composition comprising the steps of:
- (I) preparing a monomer solution comprising a cycloolefin monomer having a condensed ring made of an aliphatic ring having one or more carbon-carbon double bonds and an aromatic ring and separately preparing a catalyst solution comprising a metathesis polymerization catalyst, wherein a flame retardant is added in the monomer solution and/or to the catalyst solution, and
- (II) mixing the solutions obtained in step (I) to prepare the polymerizable composition.
