<p>ABSTRACT OF THE DISCLOSURE PROPYLENE-BASED COPOLYMER MATERIAL, FILM MADE THEREFROM, AND METHOD FOR PRODUCING PROPYLENE-BASED COPOLYMER MATERIAL A propylene-based copolymer material is provided which includes 1 to 10% by weight of a propylene-based copolymerized component (1) defined below and 90 to 99% by weight of a propylene-based copolymerized component (2) defined below and which has a melting point not higher than 140 degree C, wherein the propylene-based copolymerized component (1) is a propylene-based copolymerized component which includes 89 to 97% by weight of propylene units, 0 to 1.5% by weight of ethylene units and 3 to 10% by weight of 1- butene units and which has a melting point within the range of 145 degree C to 155 degree C, and the propylene-based copolymerized component (2) is a propylene- based copolymerized component which includes 80 to 94% by weight of propylene units, 0 to 10% by weight of ethylene units and 0 to 20% by weight of 1- butene units. A film made from the copolymer material is also provided.</p> |
