<p>PROBLEM TO BE SOLVED: To provide ethylene polymer particles, which is suitable for providing a molded article obtained by a solid phase method such as solid phase drawing molding and suitable for providing a molded article having high strength.SOLUTION: Provided is ethylene polymer particles having intrinsic viscosity [η] of 5 dl/g to 30dl/g, a high degree of crystallinity of 80% or more, and specific shapes on a surface of the particle. The ethylene polymer fine particles can be obtained by carrying out polymerization of olefins including ethylene under specific conditions using an olefin polymerization catalyst such as a solid titanium catalyst component including, for example, magnesium, halogen, and titanium.</p> |
