Abstract: The flow characteristics and rheological properties of thermoplastic polyesters and copolyesters are significantly improved by the addition of a polyamide resin thereto. In addition to improving the processability of the thermoplastic materials the polymeric additives also impart other desirable properties to the resulting manufactured products.

Abstract: Blends of the hard wax fraction obtained from the fractionation of lanolin and an ester derived from an aliphatic polyol or ether polyol and fatty acid are suitable substitutes for U.S.P. anhydrous lanolin and can be substituted therefore in cosmetic formulations (creams, lotions, etc.) without detracting from the properties of the system.

Abstract: Ester products useful as lubricants for structural resins are obtained by the reaction of mono- and polyfunctional alcohols with high molecular weight branched-chain aliphatic monocarboxylic acids. The high molecular weight acids useful for the preparation of the present esters are obtained by the free radical addition of a short-chain monocarboxylic acid and .alpha.-olefins containing 22 or more carbon atoms. The esters of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.

Abstract: The flow characteristics and rheological properties of high molecular weight thermoplastic polyamides are significantly improved by blending therewith a small amount of a polyamide derived from high molecular weight dibasic acids. In addition to improving the processability of the thermoplastic resin, the blends and manufactured articles produced therefrom have other desirable properties.

Abstract: Copolyamides derived from mixed acids (a polymeric fatty acid and short-chain dibasic acid) and mixed amines (a polyoxyalkylene diamine and a short-chain diamine) are provided. These thermoplastic resin compositions are excellent reinforcing adhesives for flexible substrates and are particularly useful as box-toe construction resins.

Abstract: Epoxidized mixed mellitate compounds useful as plasticizers for vinyl polymers such as polyvinyl chloride and which have markedly improved resistance to oils and hydrocarbon extraction have been prepared. The mixed mellitate plasticizers of this invention are trimellitates wherein two of the ester moieties are simple esters derived from monofunctional alcohols with the third ester moiety being a complex ester obtained by the reaction of a diol with an unsaturated monobasic acid subsequently epoxidized at the site of unsaturation.

Abstract: An improved process is provided herein for the preparation of immobilized transition metal catalysts containing up to about 60 wt. % bound transition metal. These catalysts are obtained by heating a hydroxylic support with an excess of a transition metal alkoxide in an inert hydrocarbon and in the presence of water.

Abstract: Flame retardant high molecular weight linear copolyesters capable of being formed into fibers and filaments and which exhibit a high degree of thermal and ultraviolet stability are obtained using ethoxylated 3,5-dibromo-4-hydroxybenzoic acid.

Abstract: Improved liquid stabilizers consisting of a metal halide and an ethoxylated alkylphenol are provided to impart superior thermal stability to PVC resins while minimizing early color formation. The stabilizers may optionally contain a polyglycerol partial ester and/or liquid fatty acid.

Abstract: High molecular weight carboxylic acids are provided. The mixed acid products of this invention typically contain a high percentage of aliphatic straight-chain monocarboxylic acids containing 22 or more carbon atoms. The monocarboxylic acids are obtained by the ozonization of high molecular weight .alpha.-olefins under controlled conditions. Using this ozonization process it is possible to obtain mixed acid products wherein the predominant acids contain 22 to 35 carbon atoms. An additional feature of this invention is the ability to obtain mixed acid products wherein acids having an odd number of carbon atoms are present in significantly larger amounts than acids having an even number of carbon atoms.

Abstract: Ester products are obtained using an immobilized supported transition metal catalyst. Esters and polyesters having improved color and containing virtually no residual metal catalyst can be obtained with this process either by direct esterification or by ester interchange.

Abstract: This invention relates to reactive liquid polyamides derived from poly-basic acids and amine residues obtained as by-products from the process for the hydrogenation of adiponitrile to hexamethylenediamine. By use of these amine residues it is possible to obtain liquid polyamide products having low amine values and manageable viscosities. The liquid reactive polyamides are useful for a variety of applications, for example, they can be blended with thermoplastic polyamide resins to impart desirable properties thereto.

Abstract: Soaps and ester-soaps of high molecular weight branched- and straight-chain aliphatic monocarboxyic acids obtained from .alpha.-olefins containing 22 or more carbon atoms are useful lubricants for structural resins. High molecular weight acids useful for the preparation of the soaps and ester-soaps are obtained by the free radical addition of a short chain monocarboxylic acid to C.sub.22.sub.+ olefin or by ozonization of the C.sub.22.sub.+ olefin. The products of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.

Abstract: This invention provides certain complex molecules which possess excellent solubility in water and excellent reactivity making them useful in the manufacture of non-woven products and processes for their preparation. The compositions are comprised of structural units derived from a higher polycarboxylic acid and about one mole of a di-epoxide per carboxyl group, about 0.5 to 1.5 moles of an alkoxy polyoxyalkylene compound and about 0.5 to 1.5 moles of an alkanolamine neutralized with a lower monocarboxylic acid.

Abstract: The present process relates to the production of crystalline 2,2-bis[3,5-dibromo-4-(2-hydroxyethoxy)phenyl] propane by cooling the molten material with shear. An especially useful aspect of this invention involves the continuous crystallization of 2,2-bis[3,5-dibromo-4-(2-hydroxyethoxy)phenyl] propane employing a scraped surface heat exchanger to achieve the desired rate of cooling and shear.

Abstract: Improved chain-stopped polyester plasticizers for polyvinyl chloride homopolymers and copolymers are provided. The plasticizers show little or no tendency to migrate from PVC, yet they are readily processable with the PVC. While being extremely compatible with PVC the present plasticizers have very low affinity for ABS and polystyrene resins and therefore can be used in applications where plasticized PVC comes in contact with these other resins.

Abstract: Water soluble mixed ester lubricants derived from triglycerides are obtained by transesterifying a triglyceride with a low molecular weight polyoxyethylene glycol in the presence of short-chain mono- or dicarboxylic acids. The mixed ester compositions of this invention are readily water soluble and are excellent lubricants for metalworking operations. Water solubility is achieved with the present mixed ester products even though they have higher triglyceride contents than previously known ester lubricants.
