Abstract
Se describe el uso de una composicion basada en dioxido de silicio como agente antibloqueador, la cual es caracterizada porque el dioxido de silicio tiene un tamaño de partícula de 2 a 8 æm, una superficie específica de 150 a 850 m²/g y un volumen de poro específico de 1.4 a 2.0 ml/g que ha sido tratado con poliol. Este dioxido de silicio puede usarse junto con un agente deslizante, como combinacion de agente antibloqueador y agente deslizante. El funcionamiento del agente antibloqueador o de la combinacion de agente antibloqueador y agente deslizante dentro del polímero es preferentemente en la forma de una mezcla. Un agente antibloqueador que se prefiere contiene pentaeritritol etoxilado como poliol en el cual la relacion pentaeritritol/etoxi cae en el rango de 1:0.5 a 1;25. El agente antibloqueador puede obtenerse por micronizacion del dioxido de silicio para dar el tamaño de partícula e impregnarlo con el poliol.
