AROMATIC-BASED POROUS FUNCTIONAL POLYMER

PURPOSE:To produce the polymer excellent in conversion of lightwaves and heat absorption properties and useful as, e.g. a clothing and an electric component excellent in heat radiation due to light absorption or heat accumulation due to light absorption by swelling coal particles with an organic solvent, an acid solvent, etc, under application of a heat and pressure treatment, etc., thereto and making the coal particles porous. CONSTITUTION:This polymer is produced, e.g. by admixing coal particles with an aqueous solution of an organic solvent, an acid solvent, caustic soda, caustic potassium, etc., and applying a heat and pressure treatment thereto preferably at
