HYPERBRANCHED POLYALKOXY METHYLSILSESQUIOXANES AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2016 - IPC C08G77/18 B82B3/00

Abstract RU 2574381 C2

FIELD: chemistry.

SUBSTANCE: disclosed novel spherical hyperbranched polyalkoxy methylsilsesquioxanes of general formula {[(AlkO)₂Si(Me)O_1/2-]_a[-(AlkO)Si(Me)O-]_b[MeSiO_1,5]_c}_n, where the sum of a, b and c is equal to 1, wherein values of a, b and c are not equal to zero, and the value of n ranges from 10 to 10000, Alk represents a C₂-C₄ hydrocarbon radical, and a method for production thereof.

EFFECT: obtaining novel nanosized spherical hyperbranched functional polyorganosilsesquioxanes, having a defined and regular set of units of different functionality, which can be used as promising precursors for producing organosilicon materials for different applications.
