  • Inhibition of polymer surface oxidation utilizing two primary antioxidants in certain polymers
    Patent number: 9321900
    Abstract: This invention relates to a polymer composition comprising: (A) a copolyester comprising residues of terephthalic acid, 1,4-cyclohexanedimethanol, and 2,2,4,4-tetramethyl-cyclobutanediol, and (B) a stabilizing composition comprising: (1) a phenolic antioxidant without a long-chain substituent; and (2) a phenolic antioxidant with a long-chain substituent, wherein the phenolic antioxidant (1) has 10 to 20 carbon atoms, wherein the phenolic antioxidant (2) has greater than 20 carbon atoms, and wherein the weight ratio of phenolic antioxidant (1) to phenolic antioxidant (2) is from 0.7:1 to 1.3:1.
    Type: Grant
