Abstract: The instant invention relates to a process which comprises modifying a conventional polyoxyalkylene polyol by capping all the hydroxyl groups of the polyol with benzyl, aryl, substituted benzyl, substituted aryl or alkyl groups having 1 to 4 carbon atoms. This process comprises reacting the conventional polyoxyalkylene polyol with an alkali metal methoxide followed by reaction with an alkali metal hydride which in turn is followed by reaction with an organic halide.

Abstract: The instant invention relates to a rubber lubricant composition characterized by complete wetting of the elastomer surface both before and after vulcanization which gives a matte finish on cooling down that remains soft and does not flake off. This comprises (1) polyoxypropylene-polyoxyethylene block copolymer having a molecular weight of the polyoxypropylene hydrophobe of about 2500 to 4000 and containing 20 to 80 percent oxyethylene groups and (2) an oxyethylated oxypropylated higher alcohol.

Abstract: There is disclosed a process for the aqueous solution or emulsion polymerization of acrylamide monomer to produce homopolymers of very high molecular weight using mixtures of water and monomer at least one of which can be contaminated with small amounts of polymerization inhibiting components. In the process, a minimum effective amount of a redox catalyst is utilized in order to obtain very high molecular weight by incrementally adding one member of a redox pair to a solution of the monomer containing a second redox pair number. The process can be initiated at ambient temperatures and pressures, and polymerization is effected without providing additional heat to the reaction mass. Utilizing monomer concentrations of about 10 to about 50 percent by weight, molecular weights of about 1,000,000 to 10,000,000 can be obtained.

Abstract: The oxidation promoting harmful effects of the presence of an alkaline catalyst in a polyoxyalkylene can be eliminated and the product made more resistant to oxidation especially at elevated temperatures by the incorporation therein of soluble salts of certain benzoic acid derivatives. The soluble salts can be formed by reaction with the alkali or alkaline earth metal ion derived from the alkaline catalyst utilized in the polymerization of the polyoxyalkylene.

Abstract: There is disclosed a process for the aqueous polymerization of acrylamide to produce polymers of high molecular weight utilizing mixtures of water and monomer, at least one of which can be contaminated with small amounts of polymerization inhibiting components. In the process of the invention, a minimum amount of a redox pair catalyst is utilized in order to obtain the desired high molecular weight polymer. The minimum amount of catalyst is automatically provided to the polymerization mixture by adding a first member of a redox pair to the polymerization mixture and intimately combining a second member of the redox pair catalyst with an organic polymer capable of forming a colloidal dispersion in an aqueous medium and adding this intimate mixture to the mixture of water, acrylamide monomer, and a first member of the redox pair catalyst.
