METHOD OF PRODUCING 'NANOPOLYPROPYLENE' - NANOCOMPOSITES OF POLYPROPYLENE AND PROPYLENE COPOLYMERS

摘要

FIELD: chemistry.;SUBSTANCE: described is a method of producing "nanopolypropylene" - nanocomposites of polypropylene and propylene copolymers. The method involves synthesis of polypropylene or a copolymer in at least one reactor for synthesis of polypropylene or propylene copolymer, synthesis of propylene block-copolymers in at least one reactor for synthesis of propylene block-copolymers. Dispersed bentonite clay nanoparticles which are pretreated with chemical substances are added to polypropylene or propylene copolymer after synthesis of polypropylene or copolymers. The chemical substances, e.g. water, alcohols, phenols, acids, CO, CO₂, NO₂, SO₂, CS₂, H₂S, diethyl ether of ethylene glycol, amines, ketones, acid amides, titanium tetrachloride, alkoxytitanium and halogens, are capable of reacting with a catalyst residue and carry out two basic functions - deactivate further functioning of catalyst and form a chemical bond between polypropylene or propylene copolymer and the dispersed bentonite clay nanoparticles.;EFFECT: low cost of producing nanocomposites of polypropylene and propylene copolymers, obtaining a new polymer material with a more homogeneous content of nanocomposites of polypropylene and propylene copolymers with improved physical and mechanical properties, high modulus of elasticity and breaking strength.;2 cl, 3 dwg, 1 tbl
