Abstract: AN ALIPHATIC POLYESTER RESIN HAVING A HIGH MOLECULAR WEIGHT AND, IN THE PREFERRED STATE, A HIGH MELTING POINT, AND EXCELLENT THERMAL STABILITY AND HUE, AND A METHOD FOR EFFECTIVELY PRODUCING THE SAME ARE PROVIDED.A METHOD FOR PRODUCING AN ALIPHATIC POLYESTER RESIN INCLUDING A MELT POLYMERIZATION STEP AND A SUBSEQUENT SOLID PHASE POLYMERIZATION STEP, USING A SULFONIC ACID GROUP-CONTAINING COMPOUND AS A CATALYST, WHEREIN THE ADDITION AMOUNT OF THE SULFONIC ACID GROUP-CONTAINING COMPOUND DURING MELT POLYMERIZATION IS 300 TO 3000 PPM WITH RESPECT TO A RAW MATERIAL MONOMER CALCULATED AS SULFER ATOMS, THE CONTENT OF THE SULFONIC ACID GROUP-CONTAINING COMPOUND DURING MELT POLYMERIZATION IS 300 TO 3000 PPM WITH RESPECT TO A PRODUCED POLYMER CALCULATED AS SULFER ATOMS, AND A RESIDUAL RATE OF THE SULFONIC ACID GROUP-CONTAINING COMPOUND AFTER SOLID PHASE AT POLYMERIZATION IS MORE THAN 50%. FURTHER, ALIPHATIC POLYESTER RESIN COMPOSITION CONTAINING A SULFONIC ACID GROUP-CONTAINING COMPOUND HAVING 2 OR MORE SULFONIC ACID GROUPS IN ONE MOLECULE IN AN ALIPHATIC POLYESTER RESIN, IN A CONTENT OF 300 TO 3000 PPM WITH RESPECT TO A PRODUCED POLYMER CALCULATED AS SULFUR ATOMS.
