Abstract: PURPOSE:To attempt to improve heat insulating property, lightweightness, voluminousness, hand, etc., by coating a base material with a compsn. contg. a specified self-dispersing type aq. vinyl resin emulsion and drying them by heating. CONSTITUTION:A compsn. contg. a self-dispersing type aq. vinyl resin emulsion having a particle diameter of 0.001-0.05mum and a number-average MW of 10,000-500,000 is obtd. by soln.-polymerizing 0.5-60wt.% monomer having a salt- forming group or a polyalkylene oxide group and a polymerizable double bond (e.g., acrylic acid) and 99.95-40wt.% monomer polymerizable therewith (e.g., methyl acrylate) in the presence of 0.05-0.5wt.% radical initiator (e.g., t-butyl hydroperoxide) based on the whole monomer and, if necessary, a chain transfer agent in an alcoholic and/or a ketone solvent at 50 deg.C - solvent reflux temp., adding, if necessary, a neutralizing agent to ionize the basic groups, adding water thereto and distilling the solvent therefrom to effect phase reversal to a water phase. Then, a base material is coated with a foam obtd. by expanding this compsn. 1.5-10-fold or the foam is cast in a mold and they are heated and dried.

Abstract: PURPOSE:To obtain the titled resin which scarcely forms agglomerates during polymerization and has a rate of polymerization, by polymerizing a vinyl aromatic monomer with a vinyl cyanide monomer in the presence of a butadiene polymer latex by using a specified surfactant. CONSTITUTION:A surfactant (D) having at least one alkenyl or alkyl group and comprising a substituted succinic acid (salt) as an essential component is obtained by reacting a 4-12C alpha,beta-unsaturated dicarboxylic acid (anhydride) (a) selected from among maleic, fumaric, itaconic and citraconic acid with an 8-40C alkylene, preferably, an 8-22C linear alkylene (b) (e.g., hexadecene) and, optionally, hydrogenating the product. A mixture of a vinylaromatic monomer (B) with a vinyl cyanide (C) is graft-polymerized in the presence of a butadiene polymer latex (A) by adding 0.1-2pts.wt., per 100pts.wt. graft monomer, component D in such a way that 0-1.0pt.wt. component D is added at the start of polymerization and 0.5-2.0pts.wt. component D is added after the start of the polymerization reaction.

Abstract: PURPOSE:To prevent the lowering in heat transfer and cooling effect by suppressing the formation of scale, by constituting a scale inhibitor on the basis of polymaleic acid with MW of 200-5,000. CONSTITUTION:Alkali metal hydroxide such as caustic soda or aqueous ammonia is added to an aqueous solution of maleic acid in a ratio of 0-150mol to 100mol of maleic acid. Subsequently, this solution is heated to 50-160 deg.C and a polymerization initiator is dripped in said solution to polymerize maleic acid. By this method, polymaleic acid represented by formula (wherein R1 and R2 are H, OH or OS3M, M is one or more component selected from a group consisting of H, an alkali metal such as Na or K, NH4 and an alkaline earth metal such as Ca or Mg and m is 3-80) is obtained and used as a main component.

Abstract: PURPOSE: The titled surfactant capable of providng stable, low-foaming emulsions, consisting mainly of a salt of a copolymer consisting of a carboxyl group or sulfonic acid group-containing unsaturated monomer and an acrylate ester monomer in a specified weight ratio.
CONSTITUTION: 85W99wt% carboxyl group or sulfonic acid group-containing unsaturated monomer (e.g., acrylic acid or vinylsulfonic acid) is mixed with 15W 1wt% ester of an 8W20C aliphatic alcohol with (meth)acrylic acid (e.g., lauryl acrylate or stearyl acrylate). Then, above 60wt% resulting monomer mixture as an essential component is copolymerized with below 40wt% different nonionic unsaturated monomer (e.g., ethyl acrylate or acrylamide). Then, the produced copolymer is neutralized into a salt, which is the purpose surfactant for use in emuosion copolymerization.

Abstract: PURPOSE:To improve the adhesion to a tile joint and provide stainproofness, water resistance, and oil resistance by using an aq. fluororesin dispersion as the essential component. CONSTITUTION:After the copolymn. of 5-95wt.% fluoromonomer, 0.5-50wt.% monomer having a salt-forming or polyoxyalkylene group, and 0-94.5wt.% vinyl monomer copolymerizable with the foregoing two monomers in an org. solvent, water is added to and then the org. solvent is removed from the copolymn. system, giving an aq. emulsion. A vinyl monomer is polymerized in the presence of the emulsion, to give an aq. fluororesin dispersion which has a solid content of 30-50wt.% and comprises an aq. dispersion of double-structured resin particles having shells wherein a fluororesin is distributed. The dispersion, if necessary after mixed with a mildewproofing agent, a defoamer, a plasticizer, etc., is mixed with a white cement when used in sealing a tile joint.
