| abstract | 1,220,384. Copolymer latex. FARBENFABRIKEN BAYER A.G. 18 March, 1968 [20 March, 1967; 25 March, 1967], No. 12880/68. Heading C3P. A copolymer latex contains in emulsified form a copolymer of 40 to 98 parts by weight of a conjugated diene, 0À1 to 50 parts by weight of at least one olefinically unsaturated comonomer, 0À1 to 10 parts of an olefinically unsaturated carboxylic acid having 3 to 6 carbon atoms and 0À1 to 10 parts by weight of a carboxylic acid or a mixture thereof, having 10 to 30 carbon atoms. The diene may be butadiene, isoprene or chloroprene. The olefinically unsaturated monomer may be acrylonitrile, methacryonitrile, ethyl acrylate, methyl methacrylate, vinyl acetate, vinyl chloride, styrene or α-methylstyrene. The olefinically unsaturated acid may be acrylic or methacrylic acid. The carboxylic acid may be a mixture of C 12 to C 18 aliphatic carboxylic acids. The latex may be prepared by emulsifying the components in an aqueous medium and polymerizing the mixture in the presence of a free radical forming catalyst at 5‹ to 100‹ C. at a pH of below 7. In the examples butadiene, a solution in styrene, (meth)acrylonitrile or methylene glutarodinitrile of a long-chain fatty acid mixture of acids containing 12 to 18 carbon atoms, and methacrylic acid are emulsified in an aqueous medium using at least one anionic emulsifier. The emulsion is polymerized with a redox catalyst system and the polymerization terminated using an aqueous solution of sodium dithionite and the sodium salt of ethylene diamine tetra-acetic acid. The latex is stabilized using styrenized xylenol and diphenylamine, and the latex is then creamed followed by the addition of vulcanizing agents, pigments and fillers. The latex mixture formed as above is used to form shaped articles by the dip-tank process. |
