A polyolefinic resin and a resin composition comprising said resin |
摘要 |
A polyolefinic resin which is a homopolymer of an olefin or a copolymer of olefins, has (i) intrinsic viscosity [ eta ] measured in decaline at the temperature of 135 DEG C in the range of 0.5 to 10 deciliter/g and (ii) content of insoluble fraction in boiling n-heptane (W) in the range of 10 to 99 weight % and shows (iii) relation between relaxation time of rubber component measured by pulse NMR at the temperature of 30 DEG C [T2H<R> (30): mu s], relaxation time of rubber component measured by pulse NMR at the temperature of 80 DEG C [T2H<R> (80): mu s] and the content of insoluble fraction in boiling n-heptane (W) satisfying the following equations: T2H<R> (80) </= 670 - 2.2 x W T2H<R> (80) / T2H<R> (30) </= 8.8 + 0.086 x W and a propylenic resin composition comprising (A) 10 to 95 weight % of the polyolefinic resin, particularly a propylenic resin which is at least one kind selected from a homopolymer of propylene and copolymers of propylene containing 4 mol % or less of other olefinic units, and (B) 90 to 5 weight % of a propylenic random copolymer having intrinsic viscosity [ eta ] measured in decaline at the temperature of 135 DEG C in the range of 0.5 to 10 deciliter/g and containing 10 to 80 mol % of olefinic units other than the propylenic unit are disclosed. The polyolefinic resin and the composition have high heat resistance and excellent mechanical properties in a wide range of modulus, show small temperature dependence of the mechanical properties and do not cause stickiness on the surface of molded articles. |
