    摘要： 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.

    摘要： A random copolymer consisting essentially of 40 to 90 mole% of propylene and 60 to 10 mole% of 1-butene, and having (A) a boiling n-heptane-insoluble content of not more than 5% by weight based on the weight of the copolymer, (B) a boiling methyl acetate-soluble content of not more than 2% by weight based on the weight of the copolymer, (C) a melting point, determined by differential thermal analysis, of 40 to 140.degree. C., (D) an intrinsic viscosity, determined in decalin at 135.degree. C., of 0.5 to 6 dl/g, (E) an elongation at break, measured by JIS K6301, of at least 300%, (F) a tensile strength at break, measured by JIS K6301, of at least 50 kg/cm.sup.2, and (G) a haze, measured by JIS K6714, of not more than 40%.The above copolymer has superior properties for production of various kinds of melt-shaped articles such as films, sheets, vessels and tubes, and can be obtained by copolymerizing propylene and 1-butene in the presence of a catalyst prepared from a solid complex containing magnesium, titanium and halogen, an organometal compound of a metal of Groups I to III of the periodic table, and an electron donor.
