摘要： Disclosed is a successively biaxially stretched film obtained by successive biaxial stretching method comprising extruding a melt of a β-crystal nucleating agent-containing polypropylene-based resin composition from a T-die, cooling the extruded resin on a chill roll, and stretching the resulting web sheet longitudinally and then transversely, wherein the longitudinally stretched sheet is made to have a degree of β-crystal orientation of less than 0.3 by the following method (I) and/or (II), optionally subjected to annealing treatment, and transversely stretched: method (I): melting the polypropylene-based resin composition containing needle crystals of a specific β-crystal nucleating agent at a temperature not lower than m.p. of the polypropylene-based resin and lower than dissolution temperature of the β-crystal nucleating agent in the polypropylene-based resin melt, and extruding the melt from the T-die at the same temperature, method (II): adjusting neck-in ratio during longitudinal stretching to 25 to 55%. The porous polypropylene film has good breakage resistance during manufacture, excellent thickness uniformity, high porosity and air-permeability, and is useful for battery separators.

摘要： The present invention provides a crystalline polypropylene-based resin molded article having an excellent impact resistance, in particular a remarkably high Izod impact strength, and a process for producing the molded article. A polypropylene-based resin molded article with an excellent impact resistance in which the β crystals of the polypropylene-based resin are unoriented can be produced by a process comprising the steps of: adding 0.01 to 0.1 parts by weight of at least one amide compound to 100 parts by weight of a polypropylene-based resin; kneading the resulting mixture at a temperature not lower than the dissolution temperature of the amide compound in the molten polypropylene-based resin until the compound dissolves in the molten polypropylene-based resin; and injecting and/or extruding the resulting melt in such a state that the amide compound has dissolved in the molten polypropylene-based resin.
