    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： Disclosed is a polymer and its preparation by reacting part of the monomers in the reactor in such a way as to obtain a high molecular weight product, and reacting at least one other portion of the monomer in the same reactor in such a way as to obtain at least one low molecular weight fraction. The products are useful in contact adhesives, particularly when blended with an aminoplast or phenoplast as a tackifier and crosslinker, and with a thickening agent such as polyvinyl alcohol.

    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.
