Patent ID: 8445618

Claim:
A process for production of a highly crystalline α-olefin polymer, the process comprising: either 1) or 2), 1) dissolving a mixture of α-olefins having at least 18 carbon atoms in a hydrocarbon solvent at a temperature of 50° C. or less and then extracting a homogeneous supernatant solution from said mixture, or 2) distilling a mixture of α-olefins having at least 18 carbon atoms, to obtain a monomer comprising 80% by mol or more of an α-olefin having from 22 to 40 carbon atoms; and polymerizing the obtained monomer in a homogeneous liquid state in the presence of a polymerization catalyst comprising (A) a double-crosslinked transition metal compound and (B) at least one component selected from (B-1) a compound capable of forming an ionic complex through reaction with the transition metal compound as the component (A) or a derivative thereof and (B-2) an aluminoxane.
