A propylene-based polymer having a melt flow rate of 0.1 to 20 g/10 min. and a melting point Tm (.degree. C.) measured by using a differential scanning calorimeter (DSC) of 147 to 159.degree. C., in which the half width HW (.degree. C.) of the melting peak measured by using a differential scanning calorimeter (DSC) and the melting point Tm (.degree. C.) satisfy the relation: HW.ltoreq.(188-Tm)/5.

Un polimero propilene-basato che ha una portata della fusione di 0.1 - 20 g/10 resoconto. e un punto di fusione Tm (degree. C.) misurato usando un calorimetro di scansione differenziale (DSC) di 147 a 159.degree. C., in cui la larghezza mezza HW (degree. C.) del picco di fusione ha misurato usando un calorimetro di scansione differenziale (DSC) ed il punto di fusione Tm (degree. C.) soddisfaccia il rapporto: HW.ltoreq.(188-Tm)/5.
