  • Propylene-based polymer and film made of the same
    Patent number: 6583254
    Abstract: A propylene-based polymer having a melt flow rate of 0.1 to 20 g/10 min. and a melting point Tm (° C.) measured by using a differential scanning calorimeter (DSC) of 147 to 159° C., in which the half width HW (° C.) of the melting peak measured by using a differential scanning calorimeter (DSC) and the melting point Tm (° C.) satisfy the relation: HW≦(188−Tm)/5.
