A crystalline higher-α-olefin polymer which is obtained from a C10 or higher α-olefin and satisfies either (1) the melting point (Tm) as measured with a differential scanning calorimeter (DSC) is 20 to 100°C or (2) in an examination of spin-lattice relaxation time (T1) by solid NMR analysis, a single T1 is observed at the temperatures not lower than the melting point; and a process for producing the α-olefin polymer with a specific metallocene catalyst. The crystalline higher-α-olefin polymer is excellent in low-temperature characteristics, rigidity, heat resistance, compatibility with lubricating oils, mixability with inorganic fillers, and secondary processability. |
