| titleOfInvention |
Novel method for preparing precipitated silicas, novel precipitated silicas and their uses, in particular for strengthening polymers |
| abstract |
The present invention relates to a novel process for the preparation of precipitated silica, comprising reacting a silicate with an acidifying agent to obtain a suspension of precipitated silica; Filtering the suspension of the precipitated silica to obtain a filter cake; Subjecting the filter cake to a disintegration operation including adding an aluminum compound; The decomposition operation is followed by a drying step. The present invention is characterized in that the polycarboxylic acid mixture is added to the filter cake during or after the decomposition operation. The present invention also relates to novel precipitated silicas and their use. |
