MODIFIED SHEET FILLER AND USE THEREOF IN MAKING NANOCOMPOSITES Russian patent published in 2010 - IPC C09C1/42 C09C3/10 C08K3/34 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry, automobile and other industries. The modified sheet filler contains at least one sheet filler and at least one modifying agent which contains at least one polymer chain E containing a carbon chain with length from C₄₀ to C₅₀₀ and a group suspended from the polymer chain E, in which values of each of R, R¹ and R² can be identical or different and independently selected from a hydrogen atom, alkyl, alkenes and aryls with C₁ to C₂₆, substituted alkyl, alkens and aryls with C₁ to C₂₆, aliphatic alcohols and ethers with C₁ to C₂₆, carboxylic acids, nitriles, oxyethylated amines, acrylates and esters with C₁ to C₂₆, and X denotes a counter-ion such as Br^- Cl^- and PF₆ ^-. Proposed is a method of preparing such a sheet filler, a nanocomposite containing a modified sheet layer, a method of preparing such a nanocomposite and an article containing the said nanocomposite.

EFFECT: invention improves barrier properties of a diaphragm, membrane, inner lining of tyres, chambers and other similar articles.
