    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aqueous solution of a copolymer, wherein the time of occupation of a reactor for producing an aqueous solution of a copolymer can be shortened by avoiding or reducing foaming. SOLUTION: In producing an aqueous solution of a copolymer comprising (a) 50-99.5 mass% of at least one ethylenically unsaturated monocarboxylic acid and/or dicarboxylic acid (monomer A), (b) 0.5-50 mass% of at least one ethylenically unsaturated compound (monomer B) selected from an ester of an amine having at least one hydroxy group with an ethylenically unsaturated monocarboxylic acid, and a monoester and diester of the amine with an ethylenically unsaturated dicarboxylic acid, and (c) up to 20 mass% of at least one other monomer (monomer C), the monomers A, B and C are polymerized in an aqueous medium in the presence of at least one foam inhibitor.

    Abstract: PROBLEM TO BE SOLVED: To more improve various performance characteristics of a thermoplastic binder, particularly the strength of a molded product produced therefrom as compared with that of the conventional corresponding products thereof. SOLUTION: A method for producing a polymer aqueous dispersion is provided. The polymer aqueous dispersion comprises an emulsion polymer, a polymer composed of at least 5 mass% of an ethylenically unsaturated monocarboxylic acid, dicarboxylic acid or dicarboxylic acid anhydride (abbreviated to an acid polymer SP) and an alkoxysilane represented by the formula SiR R R R [wherein, groups R to R denote each mutually independently an organic group and at least one of the groups denotes an alkoxy group]. The method for production is characterized by producing the emulsion polymer in the presence of at least a small amount of the alkoxysilane by an emulsion polymerization.
