POLYMERIC COMPOSITION Russian patent published in 1996 - IPC

Abstract RU 2064946 C1

FIELD: rubber-base polymeric compositions. SUBSTANCE: composition has, %: unsaturated elastomer 97.50-99.69; stabilizing agents - mixture of 4-nonyl-2-tert. -butylphenol 0.10-0.20 and 4-nonyl-2,6-di-tert. -butylphenol 0.20-2.00 at mass ratio 1:(2-10), respectively, and ethylenediaminetetraacetic acid 0.01-0.3%. Mixture of stabilizing agents of phenolic type and ethylenediaminetetraacetic acid were added to rubber or rubber latex. Properties: plasticity - index of plasticity retaining at thermoageing at 140 C for 30, 60 and 90 min - 80-95%, 76-94% and 75-94%, respectively. EFFECT: enhanced quality of composition. 2 tbl
