| description | PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition which is excellent in rigidity, impact resistance, and fluidity and besides, when a molding is formed, good in appearance of the molding, particularly in flow marks, and to provide an injection molded material comprising this thermoplastic resin composition. SOLUTION: The composition comprises a polypropylene resin in a certain range in the weight fraction, an elastomer in a certain range in the weight fraction, an inorganic filler in a certain range in the weight fraction, and a resin in a specific range in the weight fraction which has a melt tension in a specific range when measured at 190 deg.C and a winding speed of 15.7 m/min, which has a swelling ratio in a specific range when measured at 220 deg.C, an orifice L/D of 40 and a shear rate of 1.2×10 sec , and which has a length of time in a specific range, i.e., time required for (G(t)/G(0.02)) to become 0.01 which is the ratio measured at 210 deg.C of the relaxation modulus G(t) to the relaxation modulus G(0.02) at 0.02 sec. The injection molded material therefrom is also provided. |
