| titleOfInvention | Propylene-based random copolymer, composition thereof, and film and laminate comprising the same |
| abstract | PROBLEM TO BE SOLVED: To exhibit excellent low-temperature heat-sealing property comparable to linear low-density polyethylene and to have anti-blocking properties without impairing desirable characteristics inherent in a polypropylene film or sheet. To provide a propylene-based random copolymer and a propylene-based random copolymer composition from which a film or sheet excellent in slip property and rigidity can be obtained. SOLUTION: This is a copolymer of propylene and an α-olefin having 5 or more carbon atoms, the melting point (Tm (° C.)) of the copolymer measured by a differential scanning calorimeter and the number of carbon atoms in the copolymer. The content (α (mol%)) of 5 or more α-olefin units satisfies the following relational expression (I): Tm ≦ 140 and Tm ≦ 160-7α (I), and is determined by a differential scanning calorimeter. A propylene-based random copolymer characterized in that the crystallization temperature (Tc (° C.)) and the melting point (Tm (° C.)) of the polymer satisfy the following relational expression (II): Tc ≧ 0.75 Tm-15 (II) It is a polymer. |
