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.

Polymer composition

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

Microemulsions

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.

Process for lubricating synthetic fibers

This invention relates to a process for preparing a polyoxyalkylene compound comprising reacting in the presence of a base catalyst at least one alkylene oxide with a blend of diethylene glycol and a Bisphenol A component selected from the group consisting of Bisphenol A and the reaction product of one mole of Bisphenol A with 1 to 10 moles of propylene oxide and mixtures thereof.

Polyoxyalkylene lubricants of improved oxidative stability and lower

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.

Compositions having internal mold-release properties comprise a molding polymer and an oxidation stable polyoxyalkylene lubricant compound used alone or in combination with other polyoxyalkylene compounds.

Mold release agents containing oxidation stable polyoxyalkylenes

A flame-retardant, antistatic synthetic polymeric fiber which is the product of the process of coating on said fiber about 1 percent to about 12 percent by weight of a polymer composition which is the reaction product of a cross-linking agent and a polyoxyalkylene compound having as a nucleus a nitrogen containing reactive hydrogen containing compound with a diol which is halogenated.

Flame retardant antistatic additives and antistatic fibers

The present invention relates to a method of wave soldering an assembly composed of a plurality of electrical conductors disposed on a surface of a sheet of insulating material. In accordance with this method, the surface of the sheet and the conductors are contacted with a stationary wave of molten solder having a polyether admixed therewith and floating on the surface thereof. The polyether is a heteric or block copolymer of a dihydroxyphenol and at least one lower alkylene oxide. It is preferred that the alkylene oxide contain 2 to 4 carbon atoms. The alkylene oxide may be all ethylene oxide or may be a mixture with other lower alkylene oxides such as propylene oxides and butylene oxides. In any event, the copolymer should contain at least about 20 percent by weight of oxyethylene groups, balance oxypropylene groups and/or oxybutylene groups. A conventional polymeric oxidation inhibitor may also be included.

Printed circuit board soldering

A linked compound is a useful lubricant for fibers such as nylon and polyester, providing low volatility at a temperature below about 230.degree. C. and by oxidizing, leaving a low level of residue, at temperatures above about 230.degree. C.

Fiber lubricants yielding low residues upon oxidation

A flame-retardant, antistatic synthetic polymeric fiber which is the product of the process of dispersing in said fiber about 1 percent to about 12 percent by weight of a polymer composition which is the reaction product of a polyester of a polyoxyalkylene compound having as a nucleus a nitrogen-containing reactive hydrogen containing compound with a reactant selected from the group consisting of at least one of an aliphatic or aromatic diacid, anhydride or acid halide thereof and a diol wherein at least one of said reactant is halogenated.

A process for preparing a flame-retardant antistatic polymer additive useful for incorporation into the melt prior to extruding fibers or other polymers or for dispersing on fibers. Improved flame-retardant properties are obtained by including with said flame-retardant additive an effective flame-retardant proportion of a compound from group Vb of the periodic table.

Process for producing flame retardant antistatic fibers

Flame-retardant antistatic polymer additives are provided which inhibit the buildup of electrostatic charges upon the addition of such compositions to synthetic polymeric fibers, i.e., polyamide fibers, and at the same time do not contribute to the flammability characteristics of such polymeric fibers. The flame-retardant antistatic polymer compositions are useful in combinations with fibers such as polyamide, polyester, polyurea, polyurethane, polysulfonamide, polyolefin and polyacrylic fibers. The antistatic effect is obtained by the process of coating the fibers or dispersing in or on the fibers up to about 12 percent by weight of a polymer composition which is the reaction product of:
