摘要： The invention provides a sintered ethylene polymer filter that is free from molding unevenness or defects and has ultrafine and uniform filter pore diameters. An ethylene polymer composition including an ethylene polymer with a specific shape and specific properties and an antistatic agent with a specific form is used as a material for a sintered filter. According to such a composition, the ethylene polymer particles achieve enhanced fluidity when being placed into a sintering mold. Thus, the composition gives a sintered filter that has an ultrafine pore diameter and a narrow pore diameter distribution and is free from molding unevenness or defects.
