Abstract:
1. A process to slush mold a thermoplastic polyolefin composition consisting essentially of: (i) an olefin block copolymer consisting of ethylene and propylene, 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-decene, or 1-dodecene comprising one or more soft segment and one or more hard segment, (ii) optionally a linear ethylene polymer, a substantially linear ethylene polymer, or mixtures thereof consisting of ethylene and propylene, 1-butene, 1-hexene, or 1-octene, characterized as having (iii) optionally a propylene polymer having a crystallinity equal to or greater than 30 percent, wherein said composition has a Shore A hardness greater than 75, a Tg less than 45° C., and a distinct melting peak greater than 95° C. as determined by DSC, comprising the steps of: (a) forming said composition into a powder, and (b) slush molding said powder into a skin.
