Abstract: Compounds such as bis[1-(4-anilinophenoxy)-2-propyl] 4,7-dithiadecanedioate and [3-(4-anilinophenoxy)-2-hydroxypropyl] 4,7-dithiadecanedioate are provided by reactions between 4-anilinophenoxy alcohols and epoxides and a dicarboxylic acid. The bis(4-anilinophenoxy) ester products are useful as antioxidants in polymers.

Abstract: Compounds such as 1-(4-anilinophenoxy)-3-dodecanethio-2-propanol are formed by reaction between an epoxypropoxydiphenylamine and a thiol, an alcohol or an amine. The compounds produced are useful as antioxidants for natural and synthetic elastomers.

Abstract: 3,5-Di-tert alkyl-4-hydroxybenzylpyridinium salts are reacted under basic conditions with compounds containing active methylene groups to form phenolic antioxidants. For example, 3,5-di-tert.butyl-4-hydroxybenzylpyridinium chloride is reacted with 2-nitropropane to produce 1,1-dimethyl-2-(3,5-di tert.butyl-4-hydroxyphenyl)-1-nitroethane.

Abstract: N,N'-bis(4-anilinophenyl)-4,7-dithia-5-methyldecanediamide and related antioxidants are used to offer protection to unvulcanized and vulcanized polymers. They are particularly effective in stabilizing vulcanized NBR when it is exposed to high temperature aging.

Abstract: This invention relates to phenolic age resisters, said age resisters being selected from the group consisting of alkylene diols and alkylene diacetates substituted with hindered phenolic groups and to their use in the stabilization of oxidizable polymers.

Abstract: High molecular weight, linear copolyester compositions having improved thermo-oxidative stability comprising the condensation product of (A) dicarboxylic acids or the C.sub.1 to C.sub.4 lower alkyl esters thereof, (B) glycols and (C) copolymerizable hindered phenolic comonomers wherein repeat units of said hindered phenolic comonomers are present in the copolyesters in an amount ranging from about 0.1 to 10.0 mol percent based on the dicarboxylic acids or the C.sub.1 to C.sub.4 lower alkyl esters thereof.

Abstract: Method and apparatus for making expanded lead grids for use in Faure-type lead-acid storage battery plates. The finished grid has a current-collecting header of unexpanded strip and a reticulated portion expanded, guillotine style, from the strip into a plurality of paste-retaining cells bounded by skeletal elements and nodes formed during expansion. The skeletal elements and nodes extend in opposite directions through paste from substantially one face of the plate to the other and the nodes are twisted and partially flattened so as to have plateaus on the nodes which lay in planes parallel to the principal planes of the pasted plate. A ribbon or strip of lead is fed into a continuous, in-line, guillotine-type, dual expansion machine and therein expanded along its longitudinal edges to form two reticulated portions and leaving a central unexpanded portion from which a grid, header and lug are subsequently formed.

Abstract: Dialkylaminomethylphenols such as 2,4,6-tris (dimethylaminomethyl) phenol are added, preferably along with another phenolic antioxidant prior to exposure to oxidative conditions, to a stereoregular polymer, a major portion of said polymer consisting of segmeric units derived from conjugated diolefin monomers, said polymer containing transition metal catalysts, to help prevent oxidative degradation of the polymer.This application is a continuation-in-part of U.S. application Ser.
