CA 2653720

A polymeric composition comprising a polymer matrix derived from one or more polymerisable monomers and including particles comprising an inorganic oxide and having a weight average particle size of less than or equal to 400 nm contained therein, wherein said polymeric composition is obtainable by polymerising a polymerisable mixture comprising said one or more polymerisable monomers of the polymer matrix in the presence of said particles and a dispersing agent comprising an ethylenically unsaturated compound.

L'invention concerne une composition polymérique comprenant une matrice polymère dérivée d'un ou de plusieurs monomères polymérisables et incluant dans la matrice polymère des particules comprenant un oxyde inorganique et ayant une taille particulaire moyenne pondérée inférieure ou égale à 400 nm. Selon l'invention, ladite composition polymérique peut être obtenue par polymérisation d'un mélange polymérisable comprenant ledit ou lesdits monomères polymérisables de la matrice polymérique en présence desdites particules et un agent de dispersion comprenant un composé à insaturation éthylénique.
