  • High-melt-flow fiber-reinforced propylene polymer compositions
    Patent number: 4997875
    Abstract: Disclosed is a composition comprising about from 20 to 65 percent by weight of a fiber reinforcing-agent, preferably glass fiber, dispersed in as-polymerized propylene polymer material, e.g., propylene homopolymer, having a melt flow rate (MFR) of about from 55 to 430 dg/min. The composition is useful in the manufacture of large and complex fiber-reinforced articles and parts by injection molding.
