    摘要： It is an object of the present invention to provide a propylene-based polymer composition which is excellent in transparency and heat resistance (particularly, heat resistance at high heat deformation temperature) and is free from occurrence of stickiness even when it is used at a high temperature for a long period of time. The propylene-based polymer composition of the invention comprises (A) a propylene-based polymer (PP) satisfying the following requirements (1) and (2), in an amount of 1 to 99 parts by weight, and (B) a propylene/ethylene/±-olefin copolymer satisfying the following requirements (I) to (IV), in an amount of 99 to 1 part by weight, with the proviso that the total amount of the component (A) and the component (B) is 100 parts by weight; (1) the polymer (A) has a melting point (Tm), as measured by a differential scanning calorimeter (DSC), of not lower than 110°C but not higher than 170°C, (2) the polymer (A) has an isotactic pentad fraction (mmmm fraction) of not less than 90%, (I) the copolymer (B) contains constitutional units derived from propylene in amounts of 73.1 to 87.0% by mol, constitutional units derived from ethylene in amounts of 10.0 to 16.9% by mol and constitutional units derived from an ±-olefin of 4 to 20 carbon atoms in amounts of 3.0 to 10.0% by mol, (II) the copolymer (B) has an isotactic triad fraction (mm), as calculated by 13 C-NMR, of not less than 85%, and (III) the copolymer (B) has a molecular weight distribution (Mw/Mn, Mw: weight-average molecular weight, Mn: number-average molecular weight, both being in terms of polystyrene), as measured by gel permeation chromatography (GPC), of not more than 3.5.

    摘要： The present invention provides ethylene polymer particles obtained by a solid phase method such as solid phase drawing molding and capable of providing a molded article with high strength.
    The ethylene polymer particles have an intrinsic viscosity [η] of 5 dl/g to 30 dl/g, a degree of crystallinity of as high as 80% or more, and a specific shape on the surface of the particles. The ethylene polymer particles can be obtained, for example, by carrying out polymerization of olefins including ethylene using an olefin polymerization catalyst containing a solid titanium catalyst component including magnesium, halogen and titanium under specific conditions.
