PROBLEM TO BE SOLVED: To provide a propylene copolymer which stably prepares a film, laminate, fiber, sheet or molded part which exerts an extremely good low- temperature impact resistance and also has a high transparency, anti-blocking property and rigidity without deteriorating the favorable properties inert to propylene films or sheets and a propylene copolymer composition. SOLUTION: In a propylene copolymer, the comonomer unit content is 0.1 to 49 mol.%, the amount of the component eluting at (Tp-5) deg.C or higher, defining that Tp( deg.C) is the peak top temperature of the peak at the maximum temperature side in a programmed temperature fractional chromatograph, is 25 to 95 wt.%, of the total weight, and the amount of the component with a molecular weight of 10,000 or smaller, determined by gel permeation chromatograph, is 2 wt.% or less of the total weight. |
