Abstract:
1. A porous sintered body prepared in a process comprising a step of uniformly mixing polyethylene resin particles (PE resin particles) with polyethylene resin particles having functional groups having adsorbability bonded through a graft polymer chain at the surface (fg-PE resin particles), wherein the polyethylene resin of the PE resin particles and the fg-PE resin particles has a MI value measured in accordance with ASTM D1238 of 0.1 g/10 min or less and the polyethylene resin of the PE resin particles and the fg-PE resin particles has a weight-average molecular weight of 1,000,000 or more and wherein the proportion of the fg-PE resin particles being 10% by weight or more and less than 70% by weight based on the total weight of the PE resin particles and the fg-PE resin particles.
