Modification carried out from water solutions PQAS. PQAS have high superficial activity and have adsorption on a surface of minerals in process ion-changes. The optimum concentration of a modifying solution PQAS - 0,01-0,02 g/100ml. The introduction of modified minerals in rubber compositions results in activation sulfuric vulcanization. The chemical-mechanical characteristics of rubbers raise in 1,3-1,6 cases. At use modified saponite the durability of connection between rubber and metallic cord in 1,2-1,5 cases. The modification of montmorillonite by PQAS results in increase of thermodynamic compatibility of a mineral and polymeric matrix. Introduction 1 % modified montmorillonite in polystyrene or polypropylene results in improvement of the mechanical characteristics. The modification of polyamide fibbers is accompanied by increase of cohesion composites, conditional durability at a stretching. Area of used - chemical industry.
