Abstract: New liquid thickeners for aqueous liquids are obtained by capping a liquid straight chain polyoxyalkylene compound derived from ethylene oxide or ethylene oxide and at least one other lower alkylene oxide by reacting said alkylene oxides with at least one active hydrogen-containing initiator having only one active hydrogen atom. The new thickeners are prepared at a molecular weight of about 1000 to about 25,000 utilizing an alpha-olefin oxide having a carbon chain of about 12 to about 18 aliphatic carbon atoms. Both block and heteric polyoxyalkylene compounds are useful. Alternatively, the new thickeners can be made by copolymerizing ethylene oxide or mixed lower alkylene oxides in the presence of said alpha-olefin oxide. The new thickeners exhibit an unexpected increase in viscosity in aqueous systems as compared with prior art liquid polyether thickening agents.

Abstract: Hydraulic fluids or metalworking lubricants are prepared utilizing mixture of water and, as lubricants and corrosion inhibitors, an alkyl dialkanolamide, a polyoxyethylene ester, and an ethoxylated alkylaryl phosphate ester. The compositions have improved extreme pressure lubricating and wear preventing characteristics and are non-flammable. The compositions can be thickened if desired using a polyglycol-type thickener and can contain conventional corrosion inhibiting and extreme pressure lubricating additives known in the prior art. Stable concentrates comprising a phosphate ester, a polyoxyethylene ether, and an alkyl alkanolamide can be prepared.
Abstract: Anti-static polymeric films, fibers and textile yarn produced by process comprising admixing a branched chain, sulfur-containing polyester with a synthetic film- or fiber-forming polymer, extruding said film or textile fiber, and exposing said film or textile fiber to an aqueous solution containing a polyvalent metal ion reactive with the sulfate groups present in said sulfur-containing polyester. The sulfur-containing polyester is thereby fixed within the synthetic film or fiber and is resistant to extraction by water or commonly used dry cleaning solvents.

Abstract: The present invention provides new linear phosphorus- and halogen-containing flame retardant polyester additives for normally flammable polymers and coatings for normally flammable natural and synthetic films and fibers, for instance, polyester and cellulose ester films and fibers. The phosphorus- and halogen-containing polymers of the invention are water dispersible or can be rendered water-soluble. They can be prepared by reacting a phosphorus acid reactant such as phosphoric acid with at least one halogenated difunctional monomer. The water-soluble polyesters can be cross-linked to render them insoluble in water by heating together with a methylol compound.Said halogenated monomer is preferably an oxyalkylated diacid or diol and said halogen is attached either on one or more aromatic rings or on a cycloaliphatic ring.

Abstract: Polyether-based thickeners for aqueous systems having molecular weights of about 1000 to about 75,000 which are modified with alpha-olefin epoxides having about 12 to about 18 carbon atoms exhibit increased thickening efficiency in the presence of certain organic additives. These are ethoxylated phosphate esters or mixtures of said esters with water-soluble amines. The polyethers contain about 1 to about 20 percent by weight based upon the weight of the polyether of an alpha-olefin oxide. Polyether-based thickeners containing at least one of an ethoxylated phosphate ester, or said ester in admixture with a water-soluble amine, processes for the preparation of thickened aqueous systems, and thickened aqueous compositions are disclosed. The polyether-based thickeners of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.
