Abstract
LOS MATERIALES ORGANICOS NORMALMENTE SOMETIDOS A DEGRADACION EN PRESENCIA DE OXIGENO SE ESTABILIZAN POR INCLUSION DE UN FLUOROFOSFITO AROMATICO QUE TIENE, AL MENOS, UN GRUPO BENCENO LIGADO A TRAVES DE UN OXIGENO AL FOSFORO, Y, AL MENOS, UN ATOMO DE FLUOR LIGADO DIRECTAMENTE AL MISMO FOSFORO. LA ESTABILIZACION SE MEJORA TAMBIEN INCLUYENDO UN ANTIOXIDANTE FENOLICO CONVENCIONAL. MUCHOS DE LOS FLUOROFOSFITOS AROMATICOS SON COMPUESTOS NUEVOS.
