ABSTRACT:
There is disclosed a polypropylene resin composition which comprises (a) polypropylene; (b) ethylene/.alpha.-olefin copolymer elastomer having a specific range of Mooney viscosity; (c) modified polyolefin having a specific functioal group at either or both end thereof; and (d) specific compound such as stearic acid monoglyceride, stearyl diethanolamine, N-diethanol stearylamide and N-diethanol dodecanaeamide. The above composition is excellent in elasticity, peeling strength and recoating properties, can be painted immediately after degreasing without pretreatment with trichloroethane, etc. and is well suited for polypropylene bumper materials to be painted, etc.
