| titleOfInvention | Propylene resin film and process for producing the same |
| abstract | This invention provides a propylene/alpha-olefin block copolymer which comprises a propylene resin block and elastomer block consisting of a propylene and an alpha-olefin having 2 to 12 (excluding 3) carbon atoms, in which the elastomer block accounts for 5 to 30 wt.% of the whole copolymer, the xylene-soluble components of the propylene/alpha-olefin block copolymer have an intrinsic viscosity of 4.0 to 6.0 dl/g, and particles in the elastomer block satisfy the following: (1) the proportion of the particles having a machine-direction (MD) aspect ratio of 1 to 3 is 50 to 100%; (2) the proportion of the particles having an MD roundness of 1 to 1.2 is 60 to 95% and those having an MD roundness of 1.2 to 1.4 is 30% or lower; and (3) the proportion of the particles having an (MD) average particle diameter of 0.2 mum or smaller is 45 to 80% and that of the particles having an MD average particle diameter of 0.4 to 1 mum is 20 to 40%. |
