摘要： The present invention relates to an acid catalyzed thermal polycondensation process for producing amino acid polymers. More specifically, amino acid polymers are produced by thermally condensing a mixture of one or more amino acids and optionally one or more polyfunctional monomers, using an acid catalyst, while maintaining an intimate admixture. Processing techniques useful for maintaining an intimate admixture include adding to the mixture one or more processing aids, using mechanical means, and combinations thereof. The amino acid polymers produced by this process are useful as cleaning and detergent additives; fertilizer and pesticide additives; personal care product additives; dispersants for inorganic particulates, aqueous emulsions, and drilling muds; and water treatment and oil production operation additives as corrosion and scale inhibitors.

摘要： This invention is directed to a terpolymer containing as polymerized units at least one first monomer selected from the group of vinyl acetate, vinyl ethers and vinyl carbonates, at least one second monomer of an ethylenically unsaturated monocarboxylic acid, and at least one third monomer of an anhydride of a dicarboxylic acid. The terpolymer is formed by a free-radical polymerization in a nonaqueous solvent. It has further been discovered that the partial hydrolysis, saponification, and saponification followed by oxidation of this terpolymer leads to terpolymer derivatives with improved detergent properties and improved biodegradability.

摘要： Low molecular weight addition copolymers, of (1) (meth)acrylic acid esters of alcohols such as methanol and butanol with (2) esters of alcohols such as N-(.beta.-hydroxyethyl)oxazolidine and unsaturated acids such as a (meth)acrylic acid, and (3) optional .alpha.,.beta.-ethylenically unsaturated monomers such as a (meth)acrylic acid, are found to be exceptional dispersants for inorganic and organic pigments and colorants which are insoluble in organic solvents, for lacquers, and are compatible with practically all types of lacquer resins such as vinyls, nitrocellulose, and alkyds, and with many other types of lacquer film-forming materials. Usually, when small amounts of unsaturated carboxylic acids, or other polar monomers and combinations thereof, are incorporated in the polymers, they become improved pigment dispersants. Such pigment dispersions, unexpectedly, can be let down with many types of synthetic resins and used by air-drying or baking the coated articles. Lacquers for metals, paints and printing inks are examples of uses for such blends.
