    • In accordance with the present invention, there are provided cycloolefin type random copolymer compositions excellent in heat resistance, chemical resistance, rigidity, impact resistance, etc., which comprise(A) a cycloolefin type random copolymer containing an ethylene component and a cycloolefin component and having an intrinsic viscosity [.eta.] of 0.05-10 dl/g as measured at 135.degree. C. in decalin and a softening temperature (TMA) of not lower than 70.degree. C., and(B) one or more non-rigid copolymers selected from the group consisting of:(i) a cycloolefin type random copolymer containing an ethylene component, at least one other .alpha.-olefin component and a cycloolefin component and having an intrinsic viscosity [.eta.] of 0.01-10 dl/g as measured at 135.degree. C. in decalin and a softening temperature (TMA) of below 70.degree. C.,(ii) a non-crystalline to low crystalline .alpha.-olefin type elastomeric copolymer formed from at least two .alpha.-olefins,(iii) an .alpha.-olefin-diene type elastomeric copolymer formed from at least two .alpha.-olefins and at least one non-conjugated diene, and(iv) an aromatic vinyl type hydrocarbon-conjugated diene copolymer or a hydrogenated product thereof, and optionally(c) an inorganic filler or organic filler.
