PROBLEM TO BE SOLVED: To provide an embossed sheet which has a low gloss and can retain the emboss pattern formed on the major part of the sheet without causing the loss of surface or a too small sheet thickness and without detriment to the physical and mechanical properties by compounding a propylene polymer material with a partially cross-like thermoplastic olefin elastomer. SOLUTION: This compsn. comprises 40-70% propylene polymer material and 30-60% thermoplastic olefin elastomer. The propylene polymer material comprises 10-50% propylene homopolymer or copolymer having an isotactic index of 80-99%, 3-20% linear semicrystalline copolymer fraction which has a crystallinity by DSC (differential scanning calorimetry) of 20-60% and is insoluble in xylene at room or an ambient temp., and lower than 50% polymer contg. lower than 50% units derived from ethylene, a 4-8cα-olefin, or their mixture. The elastomer comprises an ethylene copolymer and a diene rubber or a terpolymer rubber. |
