Patent

CA 2759996

Described herein is microporous precipitated silica having the following physico-chemical parameters: a CTAB surface area of 50 to 300 square meters/gram, a BET/CTAB ratio of >= 1.3, and a relative breadth .gamma. of pore size distribution of <= 3.5. The precipitated silica can also have a Sears number of from 10 to 28 and a Sears number/CTAB ratio of <= 0.16. Also described herein are vulcanizable and vulcanized elastomer compositions, e.g., tires, containing the microporous precipitated silica.

Cette invention concerne la silice précipitée microporeuse présentant les caractéristiques physicochimiques suivantes : surface CTAB de 50 à 300 m2/g, rapport BET/CTAB = 1,3, et une largeur ? relative de la granulométrie = 3,5. La silice précipitée peut aussi présenter une valeur Sears de 10 à 28 et un rapport valeur Sears/CTAB = 0,16. L'invention concerne également des compositions élastomères vulcanisables et vulcanisées, par exemple pour les pneus, contenant la silice précipitée microporeuse décrite.
