Title (EN) SILICA GEL COMPOSITION AND METHOD FOR MAKING
(FR) COMPOSITION DE GEL DE SILICE ET PROCEDE DE FABRICATION
Abstract: front page image
(EN)The invention relates to silica gel compositions containing acidified cation exchanging layered silicate materials and methods for preparing such compositions. These silica gel compositions can be contacted with metallocene polymerization catalysts to produce a catalyst composition.
(FR)Cette invention concerne des compositions à base de gel de silice renfermant des matériaux acidifiés de phyllosilicate à échange cationique et leurs procédés de fabrication. Mises en contact avec des catalyseurs de polymérisation à base de métallocène, ces compositions de gel de silice produisent une composition catalytique.
