摘要： A polymerization catalyst for polyester production which contains neither a germanium compound nor an antimony compound as a major component. It contains aluminum as the main metallic ingredient, has excellent catalytic activity, and gives a polyester which is effectively inhibited from suffering thermal degradation, during melt molding, without deactivating or removing the catalyst, and is excellent in thermal stability, stability to thermal oxidation, and hydrolytic resistance. The polymerization catalyst contains as a first metallic ingredient at least one member selected among aluminum and compounds thereof and further contains a phosphorus compound represented by a specific chemical formula. The polyester produced with this catalyst is usable as fibers, films, sheets, various moldings including hollow moldings, etc.

摘要： A novel polymerization catalyst for polyesters, which does not contain any germanium or antimony compound as the main component; polyesters produced with the catalyst; and a process for producing polyesters. This polymerization catalyst is excellent in catalytic activity, little causes thermal degradation of polyesters in melt molding even when neither deactivated nor removed, and can give thermally stable polyesters which little generate foreign matter and are excellent in transparency and color. The polymerization catalyst is one which contains as the first metal-containing component at least one member selected from the group consisting of aluminum and aluminum compounds and which gives polyethylene terephthalate (PET) having a thermal stability parameter (TS) satisfying the relationship: (1) TS

摘要： To easily obtain a polyester having excellent mechanical properties, a satisfactory hue, and a high degree of flame retardancy. [MEANS FOR SOLVING PROBLEMS] The flame-retardant polyester is a polyester comprising ethylene terephthalate units as the main structural units and a phosphorus compound copolymerized or incorporated therein or is a resin composition comprising polyesters including that polyester. The flame-retardant polyester is characterized in that a polycarboxylic acid and/orpolyol having three or more functional groups capable of forming an ester bond is contained in the polyester in a total amount of 0.05-2.00 mol (per 200 mol of the sum of the dicarboxylic acid ingredient and the diol ingredient), that a specific phosphorus compound having a functional group capable of forming an ester bond is contained in the polyester in an amount of-5, 000-50, 000 ppm of the polyester in terms of phosphorus amount, and that the polyester pellet obtained has a b value of -5 to 20, an L value of 35 or larger, and a melt viscosity at 280°C of 1,000-20,000 dPa·s.
