PURPOSE:To prepare the title compsn. excellent in stability during thermal processing and resistance to oxidation by compounding a butadiene polymer with specific antioxidants. CONSTITUTION:A butadiene polymer is compounded with 2,4-di-t-amyl-6-[1-(3,5-di- t-amyl-2-hydroxyphenyl)ethyl]phenyl acrylate and an antioxidant selected from the group consisting of n-octadecyl 3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate, triethylene glycol bis[3-(3-t-butyl-4-hydroxy-5-methylphenyl)propionate], 3,9- bis[2-{3-(3-t-butyl-4-hydroxy-5-methylphenyl)propionyloxy}-1,1- dimethylethyl]-2,4,8,10-tetraoxaspiro[5.5]undecane, 2,4-bis(n-octylthio)-6-(3,5-di-t- butyl-4-hydroxyanilino)-1,3,5-triazine, and 2,6-di-t-butyl-4-methylphenol. |
