PROBLEM TO BE SOLVED: To provide a master batch which improves impact resistance and the like of a polypropylene-based resin without deteriorating its fluidity and rigidity, to provide a method for molding the above master batch, and to provide a molded product using the above master batch. SOLUTION: This master batch comprises 10-50 pts.wt. of a polypropylene- based resin and 90-50 pts.wt. of a rubber; wherein the polypropylene-based resin is characterized by being 150-700 g/10 min in MI(melt index) and >97 mol% in mmmm (stereoregularity). By using the above master batch, the impact resistance of the polypropylene-based resin can be improved without deteriorating its fluidity and rigidity. |
