Abstract: Embossed sheets having improved grain retention can be made from a polyolefin composition containing a propylene polymer material and a partially crosslinked thermoplastic olefin elastomer composition. Large parts such as automobile door and instrument panels can be formed from these sheets.

Abstract: Embossed sheets having improved grain retention can be made from a polyolefin composition containing a propylene polymer material and a partially crosslinked thermoplastic olefin elastomer composition that includes (1) 20-80 parts by weight of a thermoplastic elastomer containing (a) from 20 to 70% of a propylene homopolymer having an isotactic index greater than 90, or a crystalline propylene copolymer with ethylene and/or a 4-8 C alpha-olefin having a polymerized propylene content greater than 85% and an isotactic index of greater than 85%; (b) from 30 to 75% of an amorphous ethylene-propylene or ethylene-butane-1 copolymer, which is xylene soluble at room temperature and contains from 30 to 70% polymerized ethylene, and (c) from 3 to 30% of a semi-crystalline ethylene-propylene or ethylene-butene-1 copolymer that is xylene insoluble at room temperature and contains greater than 90% polymerized ethylene, and (2) 80-20 parts by weight of an ethylene/propylene/diene terpolymer rubber containing 1 to 10% of a
