Disclosed are propylene polymer compositions comprising a high crystalline propylene polymer, a substantially linear ethylene polymer, linear ethylene polymer or combinations thereof, an optional filler and an optional additional polymer. Said propylene polymer compositions have improved processability with a good balance of stillness and toughness which demonstrates improved scratch resistance in injection molded articles.

Rubber modified styrene-acrylonitrile (ABS) resins are provided which have three different types of rubber particles. One particle type is a small, emulsion-produced particle and another is a large emulsion-produced particle. The third particle type is a large, mass-polymerized graft copolymer particle which comprisees as its rubbery substrate a diene polymer ingredient containing at least about 80 weight percent of a polymerized diene monomer and which constitutes no more than about 30 weight percent of the total rubber components contained within the compositions of interest. The resulting compositions have very high gloss characteristics and reduced gloss sensitivity to molding condition variations.
