Abstract:
A propylene polymer composition comprising:(a) from about 55 to about 80 parts by weight of a high crystalline isotactic propylene polymer having a crystalline phase determined by differential scanning calorimetry equal to or greater than about 62 weight percent based on the weight of the high crystalline propylene polymer;(b) from about 20 to about 45 parts by weight of a substantially linear ethylene polymer, a linear ethylene polymer or combinations thereof, wherein the substantially linear ethylene polymer and linear ethylene polymer are characterized as having:(i) a density of less than about 0.93 g/cm.sup.3,(ii) a molecular weight distribution, M.sub.w /M.sub.n, of less than about 3.0, and(iii) a Composition Distribution Branch Index of greater than 30 percent;(c) from 0 to about 50 parts by weight of a filler; and(d) from 0 to about 15 parts by weight of polyethylene, polystyrene, polycyclohexylethane, polyester, ethylene/styrene interpolymer, syndiotactic PP, syndiotactic PS, ethylene/propylene copolymer, EPDM, and mixtures thereof,wherein parts by weight are based on the total weight of the propylene polymer composition.
