NANOCOMPOSITES WITH LOW PERMEABILITY Russian patent published in 2009 - IPC C08K3/34 C08K5/19 C08L25/10 C08L25/16 B60C1/00

Abstract RU 2346961 C1

FIELD: chemistry.

SUBSTANCE: invention concerns nanocomposite with low permeability, which can be applied in manufacturing of air bladders. Nanocomposite includes clay and halogenated elastomer including links derived from C₄-C₇ isoolefin where the halogenated elastomer includes also monomer link functionalised by amine. Monomer link functionalised by amine corresponds to a definite group linked to elastomer E, where functional amine group is selected out of ethoxylated amine residues of definite structure. Invention also concerns nanocomposite including clay, halogenated elastomer with links derived from C₄-C₇ isoolefin, and functionalised amine; method of nanocomposite preparation involving composition of clay, halogenated elastomer with links derived from C₄-C₇ isoolefin, and functionalised amine. Invention also concerns tyre tube or inner tyre shell including these nanocomposites; tyre or air bladder for automotive vehicles, including trucks, buses, cars, bikes etc.

EFFECT: low air permeability of finished products out of nanocomposite.
