The present invention relates to a filled polymer masterbatch based on polymers derived from latices, and to a process for preparing it. In one of its embodiments, the present invention relates to the hydrophobicizing of particles, particularly mineral particles that are hydrophilic and have surface hydroxyl groups, for example, silica, silicates, clay, alumina, titanium dioxide and the like. The invention also extends, however, to treatment of non-mineral particles, for instance carbon black. In another of its embodiments, the present invention also relates to a filled, particularly silica-filled, polymer latex. In yet another embodiment, the invention relates to a silica-rubber masterbatch, and to a process for preparing it.
La présente invention concerne un mélange maître de polymère garni à base de polymères dérivés du latex, ainsi que son procédé de préparation. Dans un de ses modes de réalisation, la présente invention concerne l'hydrophobisation de particules, en particulier de particules minérales hydrophiliques possédant des groupes hydroxyles en surface, notamment, de la silice, des silicates, de l'argile, de l'alumine, du dioxyde de titane et analogues. L'invention concerne également le traitement de particules non-minérales, à savoir de noir de carbone. Dans un autre de ses modes de réalisation, la présente invention concerne également un latex de polymères garni, plus particulièrement, de la silice garnie. Dans un autre mode de réalisation encore, cette invention concerne un mélange maître de silice-caoutchouc, et son procédé de préparation.
