Disclosed are a tubular molded article, a covering material for protecting an electric wire and a resin for contour extrusion molding which are formed from a resin composition comprising ÄIÜ a propylene polymer in an amount of 1 to 99 mass %, and ÄIIÜ an olefin-based polymer in an amount of 99 to 1 mass %, wherein ÄIÜ the propylene polymer satisfies the following requirement of: (1) a meso pentad fraction (mmmm) is 0.2 to 0.6, and (2) a racemic pentad fraction (rrrr) and (1 - mmmm) satisfy the following relation: Ä rrrr/ (1 - mmmm) Ü≤0.1. This provides a tubular molded article which is excellent in a feel, a mechanical strength and a transparency, which is not sticky and is excellent as well in a molding-ability and which is less likely to generate poisonous gasses in wasting and incinerating and are soft to the earth environment and a covering material for protecting an electric wire and a resin for contour extrusion molding which are friendly to the earth environment and less sticky and which are excellent as well in a softness and a transparency. |
