Abstract: A polyester composition includes a ligand capable of coordinating to a metal or metal ion, wherein the ligand includes at least one donor atom selected from the group consisting of a nitrogen atom, a sulfur atom, and an oxygen atom. Consequently, it is possible to inactivate a metal catalyst which adversely affects heat resistance. As a result, it is possible to obtain polyester compositions and films having excellent heat resistance, colorability, and weathering resistance. Moreover, in the process of producing a polyester, by separating and recovering a catalyst by adding a ligand which is capable of coordinating to a metal or metal ion and which includes at least one donor atom selected from the group consisting of a nitrogen atom, a sulfur atom, and an oxygen atom, it is possible to improve the heat resistance of the polyester composition.

Abstract: A polyester composition comprising a thermoplastic polyester resin and particles of a hydroxyapatite represented by the following chemical formula: Ca(PO4)1(OH)m(CO3)nYx ¢wherein Y represents any anion other than phosphate, hydroxy, and carbonate groups; 1 is 0.4 to 0.6; m is 0.1 to 0.4; n is 0 to 0.2; x is 0 to 0.2; and 3X1+m+2Xn+zXx=2 (z being the valence of the anion Y)! and having an average particle diameter of 0.01 to 10 .mu.m and a specific surface area of 50 to 500 m2/g. This composition can give a polyester film which is excellent not only in basic properties including slip properties and wearing resistance but in electrical properties, punchability, processability in metal laminate production, flavor preservation, etc.

Abstract: A polyester composition containing a ligand which is able to coordinate to a metal or a metal ion and contains as the donor atom at least one of nitrogen, sulfur, and oxygen. In this composition, the metal catalyst causative of lowering the heat resistance of the polyester can be inactivated by the ligand. The polyester composition and films made thereof are excellent in heat resistance, colorability, and weather resistance. A polyester composition improved in heat resistance can be produced by adding, in the step of producing a polyester with a metal catalyst, a ligand which is able to coordinate to a metal or a metal ion and contains as the donor atom at least one of nitrogen, sulfur, and oxygen to thereby separate and recover the catalyst.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyester composition whereby the improvement in heat resistance of a polyester composition and the improvement in productivity accompanying to catalyst recovery can be achieved by removing a metal from the composition. SOLUTION: In a polyester production process containing an esterification step using an esterification catalyst and a polycondensation step using a polycondensation catalyst, a polyester composition is produced by separating and recovering the esterification catalyst and/or the polycondensation catalyst by adding a ligand, provided the ligand contains at least one kind of donor atom which can be coordinated with a metal or a metal ion and is selected from the group consisting of nitrogen, sulfur, and oxygen.
