<P>PROBLEM TO BE SOLVED: To provide a polymerizable composition giving a molded article with low percentage of water absorption, and restrained from generation of discoloring when heated. <P>SOLUTION: This polymerizable composition contains a cycloolefin monomer, a metathesis polymerization catalyst, a phenol-based antioxidant and a phosphorus-based antioxidant, where the content of the phenol-based antioxidant is 0.1-20 pts.wt. to 100 pts.wt. of the cycloolefin monomer; and the proportion of the phenol-based antioxidant and the phosphorus-based antioxidant: (phenol-based antioxidant/phosphorus-based antioxidant) is in a range of 0.01 to 3 in terms of weight ratio. <P>COPYRIGHT: (C)2012,JPO&INPIT |
