Abstract

Polioles con por lo menos una funcion hidroxi primaria y por lo menos otra funcion hidroxi primaria, secundario o terciaria en la posicion 2 y/o 3, sonutilizados como aditivos en concentraciones de 50 ppm a 5.000 ppm a fin de reducir el contenido deacetaldehido de los productos extruidos de tereftalatode polietileno. Preferentemente se utilizan los alcoholes de azucar, tales como sorbitol, manitol o xilitol. Adicionalmente, los compuestos ionicos,preferentemente los compuestos ionicosfácilment e solubles, tales como compuestos alcalinos, pueden mezclarse en cantidades de 0,05 ppm a 50 ppm. De acuerdocon la presente, soluciones de poliol acuosas son aplicadas por aspersion en pelotillas de tereftalato de polietileno luego de lapolicondensa cion o conposterioridad a la segunda etapa de policondensacion, también conocida como polimerizacion de estado solido, o dichas pelotillas son producidas a travésde extrusion con un contenido poliol menos o igual al 25% en peso, y sonluego configura das en forma de pelotillas (pelletizadas) y mezcladas comouna mezcla madre con un poliéster antes del procesamiento.Polyols with at least one primary hydroxy function and at least one other primary, secondary or tertiary hydroxy function in position 2 and / or 3, are used as additives in concentrations of 50 ppm to 5,000 ppm in order to reduce the acetaldehyde content of the Extruded products of polyethylene terephthalate. Preferably sugar alcohols are used, such as sorbitol, mannitol or xylitol. Additionally, the ionic compounds, preferably the ionically and easily soluble compounds, such as alkaline compounds, can be mixed in amounts of 0.05 ppm to 50 ppm. In accordance with the present, aqueous polyol solutions are applied by spraying on polyethylene terephthalate pellets after the application or after the second polycondensation stage, also known as solid state polymerization, or said pellets are produced through extrusion with a polyol content less than or equal to 25% by weight, and are then configured in the form of pellets (pelletized) and mixed as a mother mix with a polyester before processing.
