Abstract: This invention relates to a process for beneficiating a silicious phosphate ore by flotation, the process comprising the steps of conditioning an aqueous slurry of phosphate ore at a pH of from 7.5 to 10.5 with a fatty acid and a fuel oil and aerating the conditioned phosphate slurry to float the phosphate, the improvement comprising conditioning the aqueous phosphate slurry prior to aeration with a water dispersible sulfo-polyester having a glass transition temperature of 28.degree. C. to 60.degree. C. and consisting essentially of repeat units from a dicarboxylic acid, a diol and a difunctional sulfomonomer.

Abstract: Disclosed are water-dispersible polyesters which impart improved water resistance and block resistance properties to printing inks. Typical polyesters contain about 90 to 97 mole % isophthalic acid, about 3 to about 10 mole % 5-sodiosulfoisophthalic acid, about 70 to about 85 mole % 1,4-cyclohexanedimethanol, and about 15 to about 30 mole % diethylene glycol, based on the total of all acid and hydroxy moiety repeating units being equal to 200 mole %.

Abstract: Disclosed are copolyester compositions derived from about 65-100 mole % 1,4-cyclohexanedicarboxylic acid, about 65-100 mole % 1,4-butanediol and about 15-35 mole % of a compound selected from the group consisting of dimer acid and dimer glycol. These copolyesters are resistant to gamma radiation.

Abstract: Disclosed are linear, water-dissipatable polyesters and polyesteramides derived from at least one dicarboxylic acid, at least one glycol of which at least 85 mole percent is a polyoxyethylene glycol, and a disulfonamido compound. The polyesters may also contain an unsaturated acid and a difunctional hydroxycarboxylic acid, an aminocarboxylic acid or a diamine. Such polymers are especially useful as adhesives, coatings, films, textile sizes and the like.

Such polymers are especially useful as adhesives, coatings, films and the like.

Abstract: A composition and method for grooming the hair are disclosed. The composition is soluble in water and mixtures of alcohol and water, and comprises a linear polyester derived from(A) at least one dicarboxylic acid,(B) at least one diol, at least 20 mole percent of said diol component being a poly(ethylene glycol) having the formulaH--OCH.sub.2 CH.sub.2 --nOHwherein n is an integer of from two to about ten, and(C) a difunctional monomer containing a -SO.sub.3 M group attached to an aromatic nucleus, wherein M is hydrogen or a metal ion.A preferred polyester is prepared from isophthalic acid, the sodium salt of 5-sulfoisophthalic acid, and a glycol component, at least a substantial portion of which is diethylene glycol. The composition may be used in solution, or blended with other compositions for use as a mixture therewith. Conventional additives, such as plasticizers, stabilizers, etc., may also be used.

Abstract: Radiation crosslinkable, water-dispersable polyesters and polyesteramides derived from monomer components which include dicarboxylic acids, poly(ethylene glycol), monomer components substituted with a sulfonate metal salt group and .alpha.,.beta.-unsaturated acids. A typical polyester is composed of 80 mole parts of isophthalic acid, 10 mole parts of 4-carboxycinnamic acid, 10 mole parts of 5-sodiosulfoisophthalate, and 100 mole parts diethylene glycol. The polyesters and polyesteramides may also include monomer components such as hydroxycarboxylic acid, aminocarboxylic acid, aminoalcohol, glycol, diamine or combinations of such components. Such polymers are useful as adhesives, coating materials, films, packaging materials and other products. The polymers can be dissolved, dispersed or otherwise dissipated in water or aqueous solutions, dried and subsequently cured by radiation.

Abstract: Disclosed is a primer coating composition for use between thermoplastic materials and metal. The primer composition comprises a polyester, at least half of the dibasic acid components of which are selected from terephthalic acid, isophthalic acid, 1,4-cyclohexanedicarboxylic acid or a mixture thereof. The polyester is either amorphous, or may contain some crystallinity to result in a melting point below about 175.degree. C. The heat of fusion of the polyester is less than about 10 calories per gram. The primer is especially useful in promoting adhesion between metal foil and cellulose acetate butyrate laminated thereto.
