Abstract

PURPOSE: The title composition particularly having improved oxidative stability at comparatively high temperatures, obtained by adding a boron compound as a stabilizer to a polar group-containing norbornen derivative.
CONSTITUTION: A) 100 parts by wt. of a ring opening polymer obtained by ring opening polymerization of a norbornene derivative containing at least one polar group, or a blend of not less than 50 wt.% of the norbornene derivative and not more than 50 wt.% of a cycloolefin compound is blended with B) 0.1W50 parts by wt. of one or more boron compounds selected from the group consisting of B2O3, H3BO3, (R1OBO)3 and (OR2)3 (R1 is H or 1W10C hydrocarbon; R2 is 1W10C hydrocarbon) to give a ring opening polymer composition having improved oxidative stability.
EFFECT: Oxidative stability prevents thermal discoloration at 200W270°C and does not cause deterioration of mechanical properties in molding.
