Abstract

Aqueous dispersions of highly polymeric esters which give alkali-resistant films are prepared by a process wherein 10 to 40 parts by weight of an acrylic or methacrylic ester of a branched chain alcohol with at least four carbon atoms and 90 to 60 parts by weight of a vinyl ester of a carboxylic acid with 2 to 18 carbon atoms are copolymerized in the presence of a protective colloid in aqueous dispersion by known methods. Specified monomers are tert. butyl acrylate and methacrylate, tert. amyl acrylate and methacrylate, ethylcyclo-hexyl acrylate and methacrylate and 2-ethylhexyl acrylate; and vinyl acetate, propionate, butyrate, hexoate, stearate and octadecylate. Specified protective colloids are acrylamide, methacrylamide and vinyl pyrrolidone polymers and copolymers, hydroxymethyl cellulose and hydroxyethyl cellulose. Emulsifiers may also be present. Polymerization may be effected in the presence of catalysts, e.g. hydrogen peroxide, potassium persulphate, ammonium persulphate, azo diisobutyramide, succinyl peroxide and redox systems. The dispersions may be compounded with softeners, pigments, e.g. barium sulphate and titanium dioxide, and other auxiliaries and used in the manufacture of paints. Examples describe the polymerization in the presence of potassium persulphate and an ethylene oxide adduct of sperm oil alcohol of (1) vinyl propionate and tert. butyl acrylate with a methacrylamide-vinyl pyrrolidone copolymer, (2) vinyl propionate and 2-ethylhexyl acrylate with a methacrylamide-vinyl pyrrolidone copolymer and (3) vinyl acetate and 2-ethylhexyl acrylate with an acrylamide-vinyl pyrrolidone copolymer.
