MODIFIED CLAYS, METHOD OF OBTAINING THEM, AND APPLICATIONS

摘要

The invention relates to modified natural clays made organophilic by means of a polar modifier for increasing their capability of bonding to organic media receiving them, which are composed of natural clays containing, in their structures, monovalent and/or multivalent metal ions and a polar modifier for modifying the surface state of said clays, which is chosen from the group of oligomers having hydrocarbon chains containing carboxylic acid functional groups. The invention is used as organophilic mineral fillers in polymers.
