Zusammenfassung:	Compositions comprising (A) cycloolefin random copolymer containing an ethylene component, and a cycloolefin component represented by they general formula ¢I! or ¢II!: (see formula I) (see formula II) (wherein n and m are each 0 or a positive integer, l is an integer of at least 3, and R1 through R10 each represent hydrogen, halogen or hydrocarbon) and having an intrinsic viscosity of 0.05-10 dl/g as measured at 135.degree.C in decalin and a softening temperature (TMA) not lower than 70.degree.C, and (B) a cycloolefin random copolymer containing an ethylene component, and a cyclo-olefin component represented by the general formula ¢I! or ¢II! and having an intrinsic viscosity of 0.01-5 dl/g as measured at 135.degree.C in decalin and a softening temperature (TMA) of below 70.degree.C, at a component (A)/component (B) weight ratio of from 100/0.1 to 100/10. The composition is particularly useful for molding an information recording base board.
