| titleOfInvention | Synthetic rubber latex |
| abstract | A butadiene synthetic rubber latex is produced by polymerising at 0 to 15 DEG C. an aqueous emulsion of synthetic rubber-forming monomeric material containing 2 to 10 parts of a water soluble soap of a soap-forming monocarboxylic acid per 100 parts of synthetic rubber monomer to a latex of 60% to complete conversion and having present during conversion of at least 10% of the original monomer 0.1 to 2 parts of an alkali metal or ammonium polyacrylate per 100 monomer, the monomer being either butadiene or a mixture of butadiene with up to 70% of a monoethylenic compound containing a CH2=C=group. Styrene, vinyl toluene, alphamethyl styrene, chlorostyrene, dichlorostyrene, vinyl naphthalene, acrylic acid, methyl acrylate or methacrylate, acrylonitrile, methacrylonitrile, methacrylamide, vinyl-pyridines, methylvinylketone and vinylidene chloride are specified comonomers. The soap may be one or a mixture of water-soluble soaps of soap-forming monocarboxylic acids e.g. alkali-metal, ammonium and amine salts of higher fatty acids having 10 to 24 carbon atoms in the molecule and rosin acids including dehydrogenated, hydrogenated, and disproportionated rosin acids. The usual sulphonated or sulphated anionic surface-active dispersing agents may also be present as may peroxides e.g., diisopropylbenzene hydroperoxide, chain stoppers and other usual aqueous polymerisation materials. |
