PROBLEM TO BE SOLVED: To obtain a poly(1-butene) resin composition having excellent high- speed moldability of uncolored or colored pipe, suitable for a pipe for cold water and warm water, especially a colored pipe for water supply and hot water supply, providing a pipe, the colored pipe for cold water and warm water and the colored pipe for water supply and hot water supply having excellent productivity, capable of reducing the costs of the pipes. SOLUTION: This poly(1-butene) resin composition comprises a poly(1-butene) resin having 0.01-50 g/10 minutes MFR, a polyethylene having 900-29,000 viscosity-average molecular weight and/or a polypropylene having 900-29 000 viscosity-average molecular weight and arbitrarily a pigment in 0.001-5 pts.wt. of polyethylene and/or polypropylene content based on 100 pts.wt. of the poly(1- butene) resin. The pipe, the pipe for cold water and warm water and the colored pipe for water supply and hot water supply comprise the composition. |
