This invention relates to a novel class of polymeric compositions which have molecular weights ranging from 300 to 3000 and are the reaction product of (a) an alkyl or cycloalkyl substituted diphenyldiamine and (b) a conjugated or nonconjugated diene. The polymeric diphenyldiamine compounds are particularly useful as an antiozonant in diene containing polymers.

This invention relates to a new process for the preparation of N-polythiodimorpholines wherein morpholine and elemental sulfur in an alcohol mixture are oxidized with an alkali metal hypohalite or an alkaline earth metal hypohalite or N-chloromorpholine to yield N-polythiodimorpholines. The process produces N-polythiodimorpholines without the use of corrosive or toxic chemicals and the product is an economical substitute for conventional rubber curatives.

Process for preparing N-polythiodimorpholines

There is disclosed a process for the preparation of N-tetrathiodimorpholine wherein an admixture of morpholine and elemental sulfur is oxidized with air or oxygen in the presence of iron salts and iron complexes to yield N-tetrathiodimorpholine.

This invention discloses a novel class of polymeric diphenylamine compounds. The compounds are produced by reacting diphenylamine with a dialkylalkenylbenzene or dihydroxyalkylbenzene having either meta or para orientation in the presence of an acid catalyst.

Polymeric compounds prepared from diphenylamine and

The invention relates to a finishing process for the removal of low level concentrations of mercaptans, sulfides and disulfides from a gas stream, especially a natural gas stream. The sulfur compounds are washed from the gas stream with a solution containing hydrogen peroxide, sodium carbonate or sodium hydroxide, and ammonia or an amine.

This invention discloses a novel class of polymeric diphenylamine compounds. The compounds are produced by reacting diphenylamine with a dihydroxyalkylbenzene having either meta or para orientation in the presence of an acid catalyst. The polymeric diphenylamine compounds are useful as antioxidants.

Polymeric compounds prepared from diphenylamine and dihydroxyalkylbenzene

There is disclosed a process for removing sulfur compounds from a gas stream. The process involves passing the gas stream containing the sulfur compounds through a mass of porous material that has deposited upon it a metal oxide, the improvement comprises the continuous or intermittent addition of an oxidizing agent and an amine.

Sulfur removal from a gas stream

A class of novel polymeric diphenylamine compounds are used to provide antioxidant protection to oxidizable polymers. In particular, the polymeric reaction products of diphenylamine and 1,4-diisopropenylbenzene are used in acrylonitrilebutadiene and styrene-butadiene rubbers to protect these rubbers in high temperature, oxidative working environments.

Polymeric antioxidants prepared from diphenyalmine and

There is disclosed a method for stabilization of polyester resins by incorporating in the resins novel polymeric diphenylamine compounds, produced by reacting diphenylamine with a dialkylalkenylbenzene or a dihydroxyalkylbenzene in the presence of an acid catalyst.

Stabilized polyester compositions

There is disclosed a method for the stabilization of polyester resins by incorporating in the resins certain types of 4-mercaptophenol derivatives.
