Abstract: The present invention relates to a polyester polymerization catalyst, comprising a solution containing an aluminum compound and an alkali compound, with water or an organic solvent or a mixture consisting of water and an organic solvent as the medium, a production method thereof, and a polyester production method, in which the product obtained by the esterification reaction or ester interchange reaction between an aromatic dicarboxylic acid or any of its ester forming derivative and a diol is polycondensed, to produce a polyester, comprising the use of said polymerization catalyst containing an aluminum compound. The present invention can provide a polyester excellent in processability and can overcome such problems as spinneret contamination, filtration pressure rise, filament breaking, film breaking and foreign matter production in the production process of products such as fibers, films, resins and bottles.

Abstract: A polymerization catalyst for polyester production which is a solution of solutes comprising an aluminum compound and an alkali compound in water, an organic solvent, or a mixture of both; and a process for producing a polyester which comprises esterifying or transesterifying an aromatic dicarboxylic acid or an ester-forming derivative thereof with a diol or an ester-forming derivative thereof and condensation-polymerizing the resultant reaction product, characterized by using the polymerization catalyst containing an aluminum compound. The catalyst can yield a polyester having excellent moldability and being usable for producing moldings such as fibers, films, resins, bottles, etc., without posing problems such as nozzle fouling, filtering pressure increase, thread breakage, film breakage, and defects caused by foreign substances.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a polyester composition which contains inorganic porous particles at a high concentration, suppressed in the drop of a limiting viscosity and contains no large-sized particles and is excellent in the particle dispersibility. SOLUTION: The method for manufacturing the polyester composition by means of a vented kneader comprises addition and mixing of the inorganic porous particles having an average particle diameter of 0.01-10 μm and a water content of less than 10 wt.%, to the polyester in the state of substantial powder and of a limiting viscosity of 0.5 or more.
