Abstract: A polyether polycarbonate block copolymer nonionic surface-active agent and method for making the same. The polyether polycarbonate surface active agent is comprised of a hydrophilic portion comprised of a polymer selected from the group consisting of a polyoxyalkylene polyether, a saccharide, a saccharide polyoxyalkylenate, a polycarbonate having a carbon dioxide content of from about 1 to 15 molar percent and mixtures thereof and a hydrophobic portion comprising alkylene and carbonate units arranged in alternating or random order to form a poly(alkylene carbonate) having a total carbon dioxide content of from about 25 to 50 molar percent and a total molecular weight of from about 300 to 10,000. The hydrophobic portion is bonded to the hydrophilic portion at each side of a reactive hydrogen. The surface active agent is prepared by polymerizing the hydrophilic portion with the hydrophobic portion in a weight ratio of about 10:90 to 90:10.

Abstract: Thermally stable polyoxyethylene polyethers prepared by oxyethylating aromatic initiators having at least two reactive hydrogens derived from amino or hydroxyl functional groups located para to each other are disclosed. These polyethers are especially suitable as solder bath oils, solder reflow oils, and heat transfer fluids for high temperature applications.

Abstract: Fiber spin finish lubricants are disclosed which are ethylenediamine initiated "reverse" polyoxypropylene-polyoxyethylene block copolymers.

Abstract: Thermally stable heat transfer fluids are disclosed which are polyoxyethylene polymers initiated with bisphenols. These polymers do not smoke excessively, volatilize, nor form sludge in high temperature heat transfer operations in open and closed systems.

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 and which washes off easily after molding whereby there is little of no ooze after several months storage. This comprises (1) polyoxypropylene-polyoxyethylene block copolymer having a molecular weight of the hydrophobe of about 1000 to 12,000 and containing 40 to 80 percent oxyethylene groups and (2) an alkyl phenol ethoxylate.

Abstract: A microemulsion of water and an alkoxylated phenol derivative which may also contain an oil and an additional surfactant.

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: The process and polyoxyalkylene compound prepared by reacting a dihydroxydiphenylsulfone with at least one alkylene oxide in the presence of a catalyst.

Abstract: Relates to lubricating thermoplastic synthetic fibers comprising the application to said fibers of a modified polyoxyalkylene polyol which polyol is modified by capping all of the hydroxyl groups with benzyl, aryl, substituted benzyl or aryl groups or alkyl groups having 1 to 4 carbon atoms.

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.
