Abstract: front page image
(EN)A polymeric composition is described which comprises an amount of one or more organic or inorganic components which are photosensitive and/or which are degraded by another ingredient of the composition and an amount of Ti02 and/or ZnO which has been doped with a second element or the reduced ZnO, this composition having a rate of deterioration of a'UV light-sensitive physical factor at least 5 % less than that of a composition having the same formulation except that it does not contain the said Ti02 and/or ZnO which has been doped with a second element or the said ZnO.
(FR)L'invention concerne une composition polymère qui contient une quantité d'un ou plusieurs composants organiques ou inorganiques qui sont photosensibles et/ou qui sont dégradés par un autre ingrédient de la composition et une quantité de Ti02 et/ou de ZnO qui ont été dopés avec un second élément ou avec le ZnO réduit. Cette composition présente un taux de détérioration d'un facteur physique sensible aux UV au moins 5 % inférieure à celui d'une composition de même formulation, à ceci près qu'il ne contient pas de Ti02 et/ou de ZnO qui ont été dopés avec un second élément ou avec le ZnO.
