PREPARATION OF POROUS BODY |
摘要 |
PROBLEM TO BE SOLVED: To provide a method for preparing a porous body, by which method molding can be carried out even when a pore-forming material in a large amount is added and a porous body with freely adjusted porosity can be given. SOLUTION: A molding material comprising a polymeric substance having dispersed therein a pore-forming material which is solid at ordinary temperatures is molded at a temperature where the pore-forming material melts to give a solid molded product, which is washed with a solvent which does not dissolve the polymeric substance but dissolves the pore-forming material to form a pore. As the pore-forming material is preferably employed an organic compound, a polyhydric alcohol having a melting point of 40-300 deg.C in particular, and as the polymeric substance is preferably employed a polystyrenic elastomer.
