POROUS RESIN ARTICLE AND METHOD FOR PRODUCTION THEREOF |
摘要 |
<p>A porous resin article which has a proportion of communicating pores of 30 % or more and is produced by a method comprising molding a resin containing a pore-forming material incorporated therein into a molded product, and then extracting the pore-forming material from the molded product by the use of a solvent, which dissolves said pore-forming material and does not dissolve the above resin, wherein the pore-forming material is particularly an alkaline compound. The above porous resin article has a high proportion of communicating pores, and thus can hold a great amount of a lubricating oil or the like, and also, is free from the formation of a rust in an iron product in an use involving the contact with a metal part or the like, even when the unextracted pore-forming material oozes out during use.</p> |
