Abstract
A METHOD FOR PRODUCING THERMOPLASTIC POLYURETHANE BY USING MACROPOLYOL OF A HIGH MELTING POINT, A CHAIN EXTENDER OF A HIGH MELTING POINT AND POLYISOCYANATE SLOW TO REACT AS WELL AS A REDUCED AMOUNT OF CATALYST FOR PRODUCING THERMOPLASTIC POLYURETHANE, BY WHICH THERE ARE PROVIDED LESS GELLED SUBSTANCE AND BURNT DEPOSITS AS WELL AS LESS REDUCTION IN PROPERTY AND DETERIORATION-WITH-TIME; AN APPARATUS FOR USE IN THE METHOD FOR PRODUCING THERMOPLASTIC POLYURETHANE; AND THE THERMOPLASTIC POLYURETHANE OBTAINED BY THE METHOD FOR PRODUCING THERMOPLASTIC POLYURETHANE. AFTER POLYISOCYANATE AND MACROPOLYOL ARE MIXED BY A HIGH-SPEED AGITATOR, CHAIN EXTENDER IS BLENDED IN THE MIXTURE THUS OBTAINED SIMULTANEOUSLY OR AT A LATER STAGE, TO PREPARE REACTION MATERIAL, FIRST. THEN, THE REACTION MATERIAL IS ALLOWED TO REACT WHILE PASSING THROUGH A PLURALITY OF STATIC MIXERS IN A STATIC MIXER PART.
