Organo-montmorillonite modified by polyionenes for polymer composites

Abstract

The technology for producing montmorillonite modified with polyionenes has been developed. It was shown that macromolecular polymer intercalation of the quaternary ammonium salt of montmorillonite intercrystalline space is accompanied by an increase in interlayer distances from 1.08 to 1.67 nm. A method for the synthesis of montmorillonite modified with polyionenes is proposed. The optimal conditions for the sorption of polymeonene molecules by montmorillonite were found: the concentration of the aqueous dispersion of montmorillonite is 1%, the temperature of the reaction medium is 40 ° C, the ratio of montmorillonite-polyionene is 3: 1, the processing time is 24 hours.
