The present invention relates to a polypropylene resin composition, a process for preparing the same, and an article molded therefrom. The polypropylene resin composition according to the Examples, which fall within the scope of the present invention, is excellent in moldability since it has high fluidity. The article molded from the polypropylene resin composition is excellent in balance betweenrigidity and impact resistance, suppressed in such defects in appearance as flow marks, and excellent in elongation and gloss. 本发明涉及聚丙烯树脂组合物、其制造方法以及由其模制的成型品。根据本发明的实施例的聚丙烯树脂组合物不仅因其具有高流动性而具有优异的成型性，而且由其制备的成型品在刚性和耐冲击性之间完美平衡，外观缺陷如流痕被抑制，且具有优异的延伸率和光泽度。
