Abstract: A process for preparing a low molecular weight water-soluble polymer comprises reacting, in an aqueous solution system, a water-soluble monomer selected from the class consisting of (a) acrylic acid, methacrylic acid, acrylamide, acrolein, methacrolein, methacrylamide, N-vinyl pyrollidone, acryloxypropionic acid and mixtures thereof, and (b) water-soluble comonomers of one or more of the monomers of (a) with from about 5-50% of the total monomers present, of a comonomer selected from the class consisting of itaconic acid, fumaric acid, maleic acid, hydroxypropylmethacrylate, hydroxyethylacrylate, hydroxypropylacrylate, hydroxyethylmethacrylate, acrylonitrile, methacrylonitrile, dimethylaminoethyl acrylate, dimethylaminoethyl methacrylate, t-butylaminoethyl acrylate, 4-vinyl pyridine, beta-hydroxyethyldimethylaminoethyl methacrylate salt, t-butylaminoethyl methacrylate, and mixtures thereof in the presence of a catalyst system which comprises an initiator and a metal salt wherein the molar ratio of the initiat

Abstract: The specification discloses a polymer and the method of using the same to prepare articles of manufacture, the composition comprising a water-soluble salt of a polymer containing pendant groups derived from an unsaturated drying oil fatty acid hydroxyamide, carboxy groups, carboxy ester groups and optionally the residues of other unsaturated addition polymerizable monomers, the carboxy units being present in a critical amount and the polymer having a critical glass transition temperature, molecular weight and the like. Aqueous coating compositions are disclosed in which the soluble polymer is either the sole polymeric vehicle or is combined with a water-insoluble polymer latex.

Abstract: Aqueous dispersions of particulate vinyl polymers, such as acrylic polymers, particularly those prepared by emulsion polymerization, which undesirably may be caused to coagulate or agglomerate to form larger particles when subjected to purification procedures, and which contain contaminants in the aqueous and polymeric phases, are purified and deodorized by contact with adsorbent carbon particles, such as petroleum coke, at a temperature above the T.sub.g of the dispersed polymer particles.
