The present invention provides long-fiber reinforced polypropylene compositions comprising: (a) about 29-77 wt % of a crystalline polypropylene resin comprising about 50-100 wt % of a propylene homopolymer; (b) about 20-50 wt % of a long-fiber reinforcing material having an average fiber length of about 3-50 mm and an average diameter of about 4-30 .mu.m; (c) about 2-20 wt % of an elastomer, a plastomer, or a mixture thereof having a melt index as measured at 190.degree. C. of about 20-150 g/10 min, wherein said elastomer, plastomer, or mixture thereof was polymerized by a metallocene-based catalyst; and (d) about 0.01-3 wt % of a radical initiator, wherein the ratio of the melt index as measured at 230.degree. C. of the crystalline polypropylene resin to the melt index as measured at 190.degree. C. of the elastomer, the plastomer, or the mixture thereof is in the range of about 0.5 to about 10.
