POLYAMIDE COMPOSITE MATERIAL MODIFIED WITH FULLERENE FILLING MATERIALS (VERSIONS) Russian patent published in 2011 - IPC C08L77/02 C08K3/04 

FIELD: chemistry.

SUBSTANCE: composite material consists of a 12-unit polyamide matrix and a modifying carbonaceous additive - fullerene C₆₀ or a mixture of fullerenes C₆₀ and C₇₀. Components are in the following ratio, wt %: fullerene C₆₀ or mixture of fullerenes C₆₀ and C₇₀ 0.001-1.0, 12-unit polyamide - the rest up to 100. In the second version, the modifying carbonaceous additive is fullerene soot with fullerene content of 3-16 wt %. The fullerene soot is added in amount of 0.01-1.0 wt %.

EFFECT: invention enables to increase the strength of the composition with increase in elasticity, raises softening, melting and destruction temperature in air, while density and water-absorption remain virtually unchanged.
