Abstract
Thermoplastic polymer alloy compositions and a process for preparing the compositions are provided comprising a blend of polypropylene, uncrosslinked ethylene copolymer, ionomeric copolymer of ethylene and .alpha.,.beta.-unsaturated C.sub.3 -C.sub.8 carboxylic acid, crosslinking agent, and silicone elastomer. The compositions may further comprise particulate filler, color concentrate and/or coloring pigment. The compositions are particularly useful for forming interior skin sheets for applications where low gloss and high scuff resistance are desired without the need for painting. A one step process for preparing moldable sheets from the thermoplastic polymer alloy compositions by in-line compounding and reactive extrusion is also provided which eliminates separate compounding and pelletizing processing steps as precursors to the sheet extrusion process.
