FUNCTIONALIZED ALUMINA PARTICLES FOR POLYMER COMPOSITES

摘要

The present invention functionalized alumina particles, to provide a method for their preparation and compositions containing them. Such a particle comprises an alumina surface-treated particles with at least one acid of the formula The ARQ, wherein A is _SO 3 H, PO 3 H 2 or PO ₂ and H _2; And R is an organic coupler; Q is a reactive residue (moiety), for example OH, NH _2, vinyl, acryloxy, methacryloxy, NCO, CO ₂ H, SH or an epoxy. These particles may be incorporated into the polymer matrix to form a composite material having excellent mechanical performance properties.
