  • Patent number: 4098764
    Abstract: This invention is directed to 1,5-bis(3',5'-dihydrocarbyl-4'-hydroxyphenyl)pentyl derivatives, including the 3-pentyl ester, amine and amide compounds. It also deals with the stabilization of organic materials by incorporating such compounds therein, either alone or in combination with a dialkyl 3,3'-thiodipropionate or a tri(alkaryl)phosphite.
    Type: Grant
    Filed: September 1, 1976
    Date of Patent: July 4, 1978
    Assignee: Uniroyal, Inc.
    Inventors: Richard A. Gencarelli, Edward L. Wheeler

    Inventors: Richard A. Gencarelli, Edward L. Wheeler
  • Patent number: 3944492
    Abstract: Derivatives of diphenylamine or phenylnaphthylamine of the types ##SPC1##Where R.sub.1, R.sub.9 and R.sub.12 are phenyl or p-tolyl groups and the remaining R's, X and Y may be alkyl or various other substituents, are useful antioxidants for lubricating oils or for various polymeric substrates (e.g. polypropylene) especially in combination with a dialkyl thiodipropionate. Typical antioxidants are 4,4'-bis-(alpha,alpha-p-trimethylbenzyl)diphenylamine made by reacting p,alpha-dimethylstyrene with diphenylamine, and N-(4-alpha,alpha-dimethylbenzylphenyl)-1-(alpha,alpha dimethylbenzyl)-2-napthylamine made by reacting alpha-methylstyrene with N-phenyl-2-naphthylamine.
    Type: Grant
