Abstract

PURPOSE:To obtain a porous sintered resin suitable as a filter, etc., by mixing two kinds of mutually compatible synthetic resin powders having different melting points, and melting and solidifying the synthetic resin powder having lower melting point. CONSTITUTION:Two or more kinds of mutually compatible synthetic resin powders having different melting points (e.g. the combination of a polyacetal homopolymer having a melting point of 175 deg.C and a polyacetal copolymer having a melting point of 165 deg.C are mixed together and charged in a mold. The mixture is heated to a temperature above the melting point of the powder having lower melting point and below the melting point of the powder having higher melting point. A porous resin material can be produced by this process.

After processing, it is placed in a heating furnace and the mold is heated. At this time, among the two types of resin powders with different melting points, the resin powder with the higher melting point is heated.
