In accordance with the present invention, there are provided 4-methyl-1-pentene polymer compositions comprising 90-10 parts by weight of 4-methyl-1-pentene polymer (A), 90-10 parts by weight of propylene polymer (B) and 70-10 parts by weight of inorganic filler (C), provided that the sum of (A), (B) and (C) is 100 parts by weight. There are also provided 4-methyl-1-pentene polymer compositions comprising 20-3 parts by weight of .alpha.-olefin copolymer (D) in addition to the abovementioned components (A), (B) and (C), provided that the sum of (A), (B), (C) and (D) totals to 100 parts by weight. These compositions as illustrated above can be processed by vacuum forming, injection blow-forming and the like, and they are excellent in rigidity at high temperatures, toughness at low temperatures and impact strength.
