PROBLEM TO BE SOLVED: To provide a method for producing a PP molded body excellent in transparency, mechanical properties and physical properties, and a PP molded body obtained by the method.SOLUTION: The polypropylene molded body is obtained by executing solid phase compression molding at 25 to 170°C to at least one direction at 1.2 times or more to a pre-molded body made of a resin composition. The resin composition is blended with a block copolymer hydride in 0.5 to 50 pts.wt. obtained by hydriding 90% or more of all the unsaturated bonds in a block copolymer, to 100 pts.wt. of polypropylene (PP), composed of at least two polymer blocks [A] essentially consisting of the repeating unit derived from an aromatic vinyl compound and at least one polymer block [B] essentially consisting of the repeating unit derived from a linear conjugated diene compound, in which, provided that the weight fraction occupied in the whole block copolymer of all the polymer blocks [A] is defined as wA and the weight fraction occupied in the whole block copolymer of all the polymer blocks [B] is defined as wB, the ratio between wA and wB (wA:w) is (30:70) to (60:40).SELECTED DRAWING: None |
