Carboxylic Acid Or Ester Groups Each Directly Attached To Separate Aryl Groups Through The Carbonyl Of The Carboxylic Acid Or Ester Group Patents (Class 524/293)
Abstract: A method of applying a coating of polyarylene sulphide to a cooking utensil in which an intimate mixture of a polyarylene sulphide with an aryl ester of an aryl alcohol is applied to the surface of the utensil and subsequently heated to evaporate the ester and cure the coating. The mixture can be a dry powder mixture, a wet powder mixture, a paste, a suspension a liquid solution or a solid solution. The preferred mixture comprises polyphenylene sulphide and benzyl benzoate.
Abstract: Thermoplastic molding materials based on impact resistant styrene polymers and polyphenylene ethers, containing an ester of an aliphatic monocarboxylic acid having 8 to 30 carbon atoms and an aliphatic or aromatic hydroxy compound having 1 to 6 hydroxyl groups.

Abstract: A composition comprising an intimate mixture of a polyarylene sulphide with an aryl ester of an aryl alcohol, the ester being in the liquid phase and the resin being a wet powder mixture, in suspension, in solution or in the form of a paste. The preferred mixture comprises polyphenylene sulphide and benzyl benzoate. There is also described a method of curing polyphenylene sulphide comprising dissolving the polyphenylene sulphide in benzyl benzoate and heating the solution so that the benzyl benzoate evaporates and the polyphenylene sulphide cures simultaneously.
Abstract: An unfilled polymeric composition having improved electrical treeing and water treeing properties comprising a polymeric component and effective amounts of a hydrocarboxyalkoxy silane and a fatty acid. These compositions are particularly useful as insulation for high voltage transmission and distribution cables.

Abstract: Propagation of electrical trees and water trees in electrical insulation made of ethylene homopolymers or copolymers with an unsaturated monomer is inhibited by the addition to the insulating composition of an organic carboxylic ester having at least one aromatic ring and at least three carboxylic ester groups, the ester being liquid at the operating temperature of the electrical equipment in which the insulation is used. The main utility of the inhibitors of this invention is in the primary insulation for power transmission cables, especially those used in high voltage applications.
Abstract: Polyethylene terephthalate molding compositions characterized by rapid crystallization are provided by combining polyethylene terephthalate and a filler or reinforcing agent with a crystallization-rate promoter comprising neopentyl dibenzoate.
Abstract: This invention relates to a composition comprising a linear, saturated polyester, such as poly(ethylene terephthalate), containing between about 4% and about 10% by weight of the poly(ethylene terephthalate) of a hydrocarbon carboxylic acid and/or an organic polymer containing pendant acid carboxyl groups, where the acid groups are neutralized by a first cation selected from Group IA of the Periodic Table of Elements and a second cation selected from Groups IIIA, IIIB and IVB. The first cation is present in an amount less than 50% of the total metal ions and neutralizes not more than 20% of the hydrocarbon acid groups or carboxylic acid groups of the organic polymer. The second cation neutralizes up to 100% of the remaining hydrocarbon acid or carboxyl acid groups. Preferably, the first cation is sodium and the second cation is aluminum. The composition can contain up to about 150% filler and a suitable plasticizer.
Abstract: Use of a selected alkali metal salt of a polycarboxylic acid has been found to impart good crystallization and mold release properties to polyethylene terephthalate molding blends.
Abstract: A composition and a method to crystallize the composition. The composition comprises a linear saturated polyester, preferably poly(ethylene terephthalate) and from 0.05 percent to 0.6 percent of sodium nitrite. The composition can contain a plasticizer, impact modifier and a filler.
Abstract: A pastable emulsion polymer comprised of carboxylated monomer/vinyl chloride/vinyl acetate terpolymer having improved strength of adhesion produced by emulsion copolymerization and containing, per polymer weight,from 60% to 98% by weight of vinyl chloride monomer units,from 1% to 29% by weight of vinyl acetate monomer units, andfrom 1% to 15% by weight of carboxyl-containing monomerunits selected from the group consisting of olefinically-unsaturated monocarboxylic acids, monoallyl esters of non-ethylenically unsaturated dicarboxylic acids, and monovinyl esters of non-ethylenically-unsaturated dicarboxylic acids. The terpolymers are manufactured by the copolymerization of vinyl chloride, vinyl acetate, olefinically-unsaturated monocarboxylic acids and/or monoallyl esters and/or monovinyl esters of non-ethylenically unsaturated dicarboxylic acids in an aqueous emulsion. The pastable terpolymers, after empasting are used for coating flexible sheet-like articles.

Abstract: A thermosetting acrylic enamel composition blended with pentaerythritol tetrabenzoate as an antiplasticizer gives superior appearance, hardness, and resistance to acid and solvents.
Abstract: Polyesters comprising residues of terephthalic acid, 1,4-butanediol and 1,6-hexanediol or polyesters comprising residues of cyclohexanedicarboxylic acid, dimer acid and 1,4-cyclohexanedimethanol used as hot melt adhesives are found to have good adhesion, low melt viscosity and good viscosity stability when blended with certain monomeric ester plasticizers.

Abstract: Use of a selected antimonate has been found to increase flame-retardancy without lowering thermal resistivity of a polyurethane terephthalate molding blend which contains an ionic hydrocarbon copolymer or ionic salt of a hydrocarbon acid and a low molecular weight compound.
Abstract: A polyester composition comprising the salt of a dimer acid, trimer or salt of a mixture of dimer acid and trimer acid, and from 0.5 to 10 percent fine particulate red phosphorous. The salt is preferably the sodium salt of the dimer and/or trimer acids. Alternately, the salt can be the sodium salt of an organic polymer having pendant carboxyl groups. The red phosphorous can contain a phosphine suppressant such as a metal hydroxide or copper compound. The preferred red phosphorous used is believed to be coated with an aliphatic polyamine and bisphenol A, epichlorohydrin condensate, reacted with acrylonitrile and ethylene oxide produced by American Hoescht as Exolite .sup.TM 405. The composition can contain a filler, plasticizer, impact modifier, and/or a polyepoxide.
