4 Methyl 1 Pentene Polymer

Abstract: [Problem] To provide a 4-methyl-1-pentene polymer that has excellent preservation stability and dissolvability when being dissolved in a solvent and that is superior in heat resistance and/or coating appearance when a coating film thereof is stretched such as when said film is bent or used in applications requiring flexibility. [Solution] This 4-methyl-1-pentene polymer (A) is a copolymer of 4-methyl-1-pentene and at least one selected from linear a-olefins having 6-20 carbon atoms, and satisfies requirements (I) and (II). (I) The endothermic end temperature (TmE) is 230°C or less in a melting (endothermic) curve as measured by DSC. (II) The exothermic start temperature (TcS) is 210°C or less in a crystallization (exothermic) curve as measured by DSC.
