Abstract: An economical and environmentally advantageous process for the continuous manufacture of unsaturated polyesters, wherein the vapors formed during the polycondensation are purified, in a two-part distillation column, to a degree where the residual content of organic starting materials is less than 1.5 percent by weight, based on the total weight of the effluent, and the unconverted starting materials are recycled to the process.

Abstract: The adhesion, especially wet adhesion, properties of conventional polymer latices are greatly improved by the incorporation of groups derived from the reaction of carbonyl groups with hydrazines therein. The hydrazine-modified groups can be present in any component of the polymer latex, but are advantageously part of the main polymer itself. Preferred main polymers are therefore those containing carbonyl units capable of reacting with hydrazine or a substituted hydrazine, especially copolymers of N-3-oxyhydrocarbon-substituted acrylamides such as diacetone acrylamide. Significantly improved wet adhesion properties are obtained even with very low proportions of the hydrazone-modified groups.

Abstract: The invention relates to the manufacture of gelatin, whereby the gelatin is obtained from fresh derms removed from scraps of hides, sinews and tendons within the three hours following the slaughter of the animal; these materials are collected together and washed in cold water then in a solution of dilute sodium hydroxide, subjected to a mechanical separation of fibres until they are reduced to paste, they are then washed several times in cold water in order to eliminate the albumin of the blood, the paste thus washed and rinsed is filtered by pressing until a cake is obtained which is formed of pure collagen; said latter may be stored after dehydration for an indefinite length of time; it may then be subjected to the final cooking, producing a gelatin broth subjected to gelling on a conveyor belt circulating in a chamber maintained at 5.degree. C.

Abstract: The present invention is concerned with thermoplastic terephthalic acid copolyesters which crystallize more rapidly than homopolyethylene terephthalate and are based on a diol component which is about 98 to 99.9 mol % of ethylene glycol and the balance 2-ethylhexane-1,3-diol. The acid component may be up to about 10.0 mol % of other than terephthalic acid or its dimethyl ester.This invention is also concerned with a process of synthesizing such copolyesters by esterifying or transesterifying the acid and diol components between about 150.degree. and 250.degree. C. in the presence of appropriate catalysts. The condensation product may be subject to polycondensation at about 200.degree. to 300.degree. C. under reduced pressure in the presence of esterification catalysts. In a preferred embodiment the 2-ethylhexane-1,3-diol is added after the initial reaction between the acid component and the ethylene glycol and preferably after the degree of polycondensation is greater than 4.

Abstract: Water and serum soluble cholesterol compounds are prepared by reactively combining a lower acid ester of cholesterol with a peptide or protein as solubilizing agent. The water-soluble cholesterol compounds can be lyophilized and added to serum as a standard for the determination of cholesterol in biological fluids by traditional saponification methods.

Abstract: A method for processing soy protein from defatted soybean flakes. Flakes are mixed with water and heated to an elevated temperature of from about 55.degree. C. to about 70.degree. C. to extract solubles therefrom. The extract liquor is cooled over a period of time of from at least one to three hours to a temperature of from about 5.degree. C. to about 10.degree. C. resulting in curd and whey. The curd is separated from the whey and is preserved preferably by either freeze-drying or spray-drying. The curd can be redissolved in water, precipitated by addition of acid, followed by washing of the curd precipitate, adjustment of pH of the washed curd precipitate and drying thereof. The whey from which the curd of the initial extract was separated may be processed by a series of steps generally involving precipitation of additional curd, washing or redissolution of the curd, adjustment of pH, and drying the curd.

Abstract: Protein sources are subjected to hydrolysis by the action of specific proteases under neutral conditions and are then reacted with water soluble bivalent metal salts in an aqueous alkaline media to form metal proteinates which are then buffered thereby forming biologically acceptable metal proteinates which are protected from adverse acid or alkaline destruction.

Abstract: A citrate-stabilized blood plasma is frozen and thawed, the undissolved cryoprecipitate is separated and is rich in factor VIII protein. The residual liquid is treated with cation and anion exchangers, either sequentially or in admixture, to separate calcium and citrate ions therefrom. The residual plasma is then subjected to adsorption to remove a fraction which is eluted and precipitated, enriched in factors II, VII, IX and X. The liquid left from adsorption is subjected to further adsorption with silicic acid, leaving a storage-stable serum. The silicic acid is eluted to dissolve adsorbed fibrinogen which then is re-precipitated.

Abstract: I disclose thermosetting unsaturated polyesters which I produce from a mixture of glycols and oligomers. The mixture is a waste stream from a process for the production of linear polyesters from glycols and terephthalic acid. Prior to this invention, the waste stream had to be burned or buried. Now I can make useful polyester resins from them.

Abstract: A waste stream of non-volatiles is recovered (NVR) as a by-product from the oxidation of cyclohexane to cyclohexanone and chlohexanol in the process for making adipic acid. The NVR is dehydrated, and then reacted with an esterifying polyol to form a polyester polyol which was found to be useful in the dispersion of vinyl resins. Those polyester polyols with low acid numbers of less than 10, and ,referably less than 2, were found to be most effective as vinyl dispersion plasticizers. A particularly useful end-product is a tough vinyl resin film having a Shore A hardness of approximately 55. End-products may also be used in wire coatings and coverings.

Abstract: Polyamides and polyesters having greatly improved resistance to static electricity buildup are obtained by the incorporation of about 0.1 to 20 weight percent poly(alkylene ether) esters of polybasic acid. The antistatic properties of these polymers is significantly improved when poly(ethylene oxide) esters of dimer and trimer acids are employed.
