| titleOfInvention |
Novel method of preparing precipitated silicas, novel precipitated silicas, and their uses, in particular for reinforcing polymers |
| abstract |
The present invention relates to reacting a silicate with an acidifying agent to obtain a precipitated silica suspension; filtering the precipitated silica suspension to obtain a filter cake; performing a decomposition operation comprising adding at least one aluminum compound to the filter cake; It relates to a novel method for preparing precipitated silica, in which a drying step is performed after the decomposition operation. The invention is characterized in that at least one polycarboxylic acid is added to the filter cake during or after the cracking operation. The present invention also relates to novel precipitated silica and uses thereof. |
