METHOD OF STABILIZING EMULSION-POLYMERIZATION RUBBERS Russian patent published in 1998 - IPC

Abstract RU 2123015 C1

FIELD: rubber industry. SUBSTANCE: stabilization is provided by polymer amine antioxidants, in particular, by product of interaction of (i) low- molecular (co)polymer based on diene monomers with number-average molecular weigh 600-2000, containing units of grafted maleic anhydride, in amount 10 to 30 wt % with (ii) p-aminodiphenylamine at weight ratio 1:(0.9-1.9), respectively, or with (iii) p- aminodiphenylamine and sterilely hindered phenol at weight ratio of maleic anhydride to p-aminodiphenylamine and sterilely hindered phenol 1:(0.9-1.9):(0.04-1.60). Percentage of antioxidant is 0.15 to 5.00% based on weight of rubber. EFFECT: increased aging resistance of rubber and facilitated introduction of antioxidant. 8 tbl, 20 ex
