Patent ID: 7569642

Claim:
A higher olefin polymer having a polar group which is produced by subjecting to an incorporation reaction of a polar compound or halogen compound into a higher α-olefin polymer satisfying the requirements of the following (1) and (2), which is obtained by polymerizing one or more higher α-olefins having 10 or more carbon atoms or copolymerizing one or more higher α-olefins having 10 or more carbon atoms with one or more other olefins: (1) the content of units of a higher α-olefin having 10 or more carbon atoms is 50 mol % or more; (2) a single peak X1 which is ascribed to crystallization of a side chain derived from the higher α-olefin and observed at 15 deg <2θ<30 deg in a wide-angle X-ray scattering intensity distribution is observed.
