METAL-DEACTIVATING POLYMER COMPOSITION Russian patent published in 2012 - IPC C08L23/02 C08K5/134 C08K3/22 C08K5/526 

FIELD: chemistry.

SUBSTANCE: composition contains a polyolefin, sterically hindered phenol of the following formula: where groups X, which can be identical or different, have the following formula: where R1 and R4, which can be identical or different, are an alkyl group having from 1 to 8 carbon atoms; R2, R3, R5, and R6, which can be identical or different, are hydrogen or an alkyl group having from 1 to 8 carbon atoms, a hydrotalcite and/or bis(2,4-dicumylphenyl)pentaerythritol diphosphite. The disclosed polymer composition exhibits efficient metal deactivation and can therefore be used to make objects in contact with metals which cause decomposition.

EFFECT: high resistance to decomposition under the action of a metal.
