POLYMER ANTI-AGEING PASTE FOR BUTADIENE-NITRILE BASED RUBBER Russian patent published in 2010 - IPC C08L27/06 C08L9/02 C08K5/18 C08K5/09 C08K5/3412 C08L13/00

Abstract RU 2383567 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in the rubber industry for making vulcanised butadiene-nitrile based rubber with high thermal-oxidative resistance. The polymer anti-ageing paste contains polyvinyl chloride, plasticiser, stearic acid, molten mass of anti-ageing agents containing N-isopropyl-N-phenyl-n-phenylenediamine, polymer of 2,2,4-trimethyl-1,2-dihydroquinoline ε-caprolactam.

EFFECT: reduced viscosity of the paste which simplifies its further processing on rubber mixing equipment, increased thermal-oxidative resistance of the rubber.
