titleOfInvention | Propylene-ethylene block copolymer |
abstract | (57) [Summary] [PROBLEMS] To improve stiffness and surface hardness, improve impact resistance and high hardness by improving crystallinity, and improve fatigue characteristics, abrasion resistance, dimensional stability, chemical resistance, A novel propylene-ethylene block copolymer excellent in moldability and the like is provided. SOLUTION: The propylene-ethylene block copolymer has an isotactic pentad fraction (IPF) of a cold xylene-insoluble portion and an intrinsic viscosity [η] of 100 ≧ IPF ≧ 95.0-6. 788 × log [η], and the propylene-ethylene copolymer t The an δ area (−30 ° C. or less) and the weight fraction of the cold xylene-soluble portion are: (tan δ area / weight fraction of the cold xylene-soluble portion) ≧ 0.6 The propylene-ethylene block copolymer which satisfies the following relationship, and the propylene-ethylene block copolymer obtained by using a specific polymerization catalyst. |
