摘要： Disclosed is an ethylene polymer particle which can be obtained by a solid phase process such as solid phase drawing, and is suitable for producing a molded article having high strength. Specifically disclosed is an ethylene polymer particle having a limiting viscosity [η] of 5-30 dl/g and a high crystallinity of not less than 80%. This ethylene polymer particle has a specific shape in the particle surface. The ethylene polymer particle can be obtained by performing a polymerization of an olefin containing ethylene under specific conditions using an olefin polymerization catalyst containing a solid titanium catalyst component comprising, for example, magnesium, a halogen and titanium.
