PROCESS FOR PRODUCTION OF PRECIPITED SILICA, PRECIPITED SILICA, USE, POLYMER COMPOSITION, AND, ARTICLE The invention relates to a process for the preparation of a new precipitated silica, wherein: a silicate is reacted with an acidifying agent in a manner to obtain a silica suspension; said silica suspension is filtered to obtain a filter cake; said filter cake is subjected to a liquefaction operation in the absence of an aluminum compound; wherein a mixture of polycarboxylic acids is added to the filter cake during or after the liquefaction operation. It also refers to new precipitated silicas and uses thereof. |
