Definitions
- the present invention relates to a composition and a method for producing polyester.
- the polycondensation is catalyzed, stabilized and accelerated by the composition in the process according to the invention.
- DE 199 08 628.1 discloses a catalyst system consisting of a glycolic suspension of a very fine-grained carrier substance with a large inner surface, in the pores of which catalytically active metal compounds are adsorbed. Phosphonic acid compounds are also used as stabilizers for the polycondensation. In the examples, 2-carboxyethanephosphonic acid (phosphonopropionic acid) is used as a stabilizer. In addition, it is required that the time at which the stabilizer is added is different from that at which the catalyst is added and that it is as far as possible in time.
- stabilizers such as phosphoric or phosphorous acid, 'simple' phosphonic acid esters or 'simple' glycol phosphates or carboxymethanephosphonic acid do not have a polycondensation accelerating effect; on the contrary, if the phosphorus concentration is increased, the polycondensation rate decreases - the catalyst is partially separated by the stabilizer blocked.
- DE 4432839 discloses the use of tris-triethylene glycol phosphate as a stabilizer in antimony- and germanium-catalyzed polyester production processes in order to adjust the turbidity of the polymer.
- Polyalkylene glycol phosphate esters are known in the art as typical stabilizers and, with other conventional catalysts such as antimony, germanium, titanium or tin, do not accelerate the polycondensation.
- EP-A-589197 describes polyalkylene glycol phosphate esters as flame-retardant comonomers.
- carboxyphosphonic acid compounds are also disclosed as polycondensation accelerators in polyester production in a concentration of 30 to 900 ppm based on the phosphorus of the carboxyphosphonic acid compound.
- the carboxyphosphonic acid compounds bring about crosslinking of the polymer chains and at the same time protect against thermal and thermo-oxidative polymer degradation.
- transesterification catalyst In transesterification processes, it is also common to block the transesterification catalyst with the appropriate amount of phosphorus compounds so as to avoid the damaging effect of the transesterification catalyst on the polycondensation. Only after this blocking, the polycondensation catalyst is added and the corresponding polycondensation stabilizer even later.
- the object of the present invention is to provide a composition for catalysis in a process for the production of polyester suitable for bottles, films, foils, fibrous materials and engineering plastics, and an improved process for the production of polyester.

- Example 8 and Comparative Example 7 were dried in a pilot tumble dryer at 170 ° C for 8 hours in a vacuum (residual moisture ⁇ 30 ppm), processed with a simple tool in a Boy 50 T2 laboratory preforming machine to form preforms and bottles therefrom in an Ecomax 10/2 laboratory blowing machine manufactured by Krupp Corpoplast with double tools under standard conditions, then coated on a laboratory scale with SiO 2 and the shape and pressure resistance and the AA content of the bottles tested.
- the mechanical parameters corresponded to the usual results with market products, the AA content was below the detection limit of the method.
- Example 9 The products from Example 9 and Comparative Example 8 were dried at 160 ° C. for 16 hours and then spun in a chip spinning mill to a POY using standard technology.
