Patent
CA 2320367
The invention concerns an association in dry form, comprising: microfibrils whereof the mean diameter is less than 0.8 µm; and at least one mineral particle. It also concerns a method for preparing said association, which consists in preparing a suspension comprising the microfibrils and the mineral particles, which are then dried. Finally, the invention concerns the use of such an association in compositions comprising (co)polymers including elastomers, thermoplastic polymers, their alloys and mixtures.
La présente invention a pour objet une association se présentant sous forme sèche, comprenant: des microfibrilles dont le diamètre moyen est inférieur à 0,8 µm, et au moins une particule minérale. Elle a de même trait à un procédé de préparation de ladite association, dans lequel on prépare une suspension comprenant les microfibrilles et les particules minérales, que l'on sèche. Enfin, l'invention concerne l'utilisation d'une telle association dans des compositions comprenant des (co)polymères dont les élastomères, les polymères thermoplastiques, leurs alliages ou leurs mélanges.
