The present invention provides a polypropylene-based resin composition, which comprises of a) a polypropylene; b) an ethylene 1-octene copolymer in which r 1 r 2 <1 (herein, r 1 =k 11 /k 12 , r 2 =k 22 /k 21 , k 11 is a growth reaction rate constant when ethylene is added to a growth chain in which an end active site is ethylene, k 12 is a growth reaction rate constant when octene is added to a growth chain in which an end active site is ethylene, k 22 is a growth reaction rate constant when octene is added to a growth chain in which an end active site is octene, and k 21 is a growth reaction rate constant when ethylene is added to a growth chain in which an end active site is octene); and c) an inorganic filling agent, and a part for vehicles manufactured by using the same. |
