Abstract: Saturated polyester compositions stabilized against thermal degradation by the addition of small amount of a synergistic stabilizing combination of a 5 or 6 membered, cyclic organic carbonate and an antioxidant selected from the group consisting of certain alkylated phenols, polyphenols, alkylphosphites, arylphosphites, aromatic amines and aromatic diamines.

Abstract: A non-chemically inhibited starch is prepared by controlled heating at a specified pH of an aqueous suspension of an amylose-containing starch in intact granule form and an inorganic salt effective in raising the gelatinization temperature of the starch.

Abstract: A copolyester is formed of at least one symmetrical aromatic dicarboxylic acid member, at least one dimer acid, and at least one C.sub.2 --C.sub.10 glycol, and at least one polyester polyol member. The polyester polyol member is either a polycaprolactone polyol having a molecular weight of 500-5,000, or a mixture of a polycaprolactone diol having a molecular weight of 300-5,000 and a nonpolymeric polyol. The resultant thermoplastic copolyester has a glass transition temperature of less than 25.degree.C and a polymer melting temperature greater than 70.degree.C, and is useful both as a hot melt adhesive by itself and as an ingredient of both pressure sensitive and non-pressure sensitive hot melt adhesive formulations. In producing the copolyester, an intermediate copolyester of the symmetrical aromatic dicarboxylic acid member, the dimer acid, and the glycol is chain extended by reaction with the polyester polyol member in a 2-6 hour reaction at about 225.degree.-270.degree.C under a vacuum of about 1-30 mm.

Abstract: A process for coloring hair and the hair coloring compositions employed therefor are disclosed. Said process essentially comprises treating the hair with an acid dye in the presence of an aqueous solution of a water soluble cationic polymer selected from the group consisting of water-soluble acid salts of aminoalkyl esters of homo- and copolymers of unsaturated carboxylic acids having from 3 to 5 carbon atoms. Said hair coloring composition essentially comprises an aqueous solution of a water-soluble acid salt of an aminoalkyl ester of a homo- or copolymer of said unsaturated carboxylic acids in combination with a small amount of an acid dye.

Abstract: An adhesive composition suitable for laminating thin foils to substrates, especially paper, is disclosed consisting essentially of an aqueous solution of a carboxylated vinyl acetate copolymer and a compatible, foil adherent, latex adhesive. These adhesives have the unique viscosity, drying, and adhesive properties required of foil laminating adhesives which were previously available only in foil laminating adhesives incorporating a casein thickener.

Abstract: A process for setting hair is disclosed comprising the steps of applying to the hair a solution of sulfonated polymer selected from the group consisting of sulfonated polystyrene, sulfonated interpolymers of styrene and ethylenically unsaturated comonomers, and soluble salts of said sulfonated polymers, setting the hair in the desired configuration, and allowing the hair to dry while it is retained in the desired configuration.

Abstract: Retort starches comprising blends in specified proportions of starch and high amylose starch, said starches being hydroxypropylated and inhibited to a specified degree. These retort starches exhibit good thin-thick properties and high end viscosities and are especially suited for use in foods such as gravies and puddings.

Abstract: Modified starch products are prepared by reacting a starch, in an aqueous slurry or dispersion, with a salt of the reaction product of a 2-alkyl-2-oxazoline and phosphorus oxychloride, under controlled conditions.

Abstract: A process of sizing paper with a reaction product of maleic anhydride with a vinylidene olefin.

Abstract: Graft copolymers are prepared by condensing a polyamideamine substrate with starch under controlled reaction conditions. Aqueous solutions of the resulting graft copolymers function as superior wet strength additives in the paper making process.

Abstract: Water-soluble homo-and co-polymers of styrene and salts thereof having a degree of substitution from about 0.7 to about 1.3 sulfonate groups per unit of styrene are useful for treating gastric or duodenal ulcers.

Abstract: Anaerobic curing compositions useful as anaerobic adhesives and sealants are described. These compositions comprise mixtures of polymerizable acrylic and substituted acrylic monomers together with a two-component catalytic system comprising a diazosulfone compound used in conjunction with ortho-sulfobenzimide.

Abstract: Starch-based alkaline curing corrugating adhesives, containing a novel crosslinking additive comprising acetoacetamide-formaldehyde condensate, are useful in the manufacture of corrugated paperboard. These adhesives are characterized by their excellent stability with respect to viscosity, their long pot life and their ability to form water-resistant bonds, particularly after aging.

Abstract: This invention relates to a rapid method for drying foodstuffs and the foods dried thereby. In particular, the method disclosed involves comminuting the foodstuff, blending therewith starch in an amount of 20 to 96% by anhydrous weight of the total mixture and drum drying to a desired moisture level. The resulting dried and extended foodstuff is superior to conventionally dried foodstuffs in color, fragrance, flavor retention and storage stability.

Abstract: A cold water resistant adhesive composition is disclosed which exhibits an optimum balance of cold water resistance and removability when employed for labeling of bottles which will be used under conditions of extreme humidity. The adhesive comprises a mixture of starch, styrene-maleic anhydride resin, peptizer, water and sufficient alkali to obtain a pH of 8.0 to 11.0 with at least 20% of the alkali present in the form of a "fixed alkali".
