A METHOD FOR CRYSTALLIZATION OF ORGANIC OLIGOMER, EPOXY RESIN COMPOSITION COMPRISING ORGANIC OLIGOMER OBTAINED BY SAID METHOD AND EPOXY RESIN CURED PRODUCT

摘要

FOR THE PURPOSE TO PROVIDE A METHOD TO CRYSTALLINE ORGANIC OLIGOMER OF LOW CRYSTALLIZING SPEED WITHOUT USING A SPECIFIC APPARATUS AND WITHOUT WASTING HUGE ENERGY, AND TO PROVIDE EPOXY RESIN COMPOSITION SUITED AS THE SEALING MATERIAL FOR SEMI-CONDUCTOR CONTAINING THE ORGANIC OLIGOMER OBTAINED BY SAID METHOD FOLLOWING METHOD IS FOUND OUT. THAT IS, THE METHOD FOR CRYSTALLIZATION OF ROGANIC OLIGOMERS COMPRISING, AFTER FLUIDIZING POWDERED OR GRANULATED SEED CRYSTALS OF ORGANIC OLIGOMER IN AN APPARATUS WITH POWDER STIRRING MECHANISM, POURING LIQUID OF SAME CRYSTALLIZABLE ORGANIC OLIGOMER CONTINUOUSLY OR BY BATCH INTO SAID APPARATUS SO THAT TO MIX AND DISPERSE, THEN GROWING UP CRYSTALS OF THE ORGANIC OLIGOMER IN SAID APPARATUS.
