Abstract: A polymer latex is prepared by dispersing 100 parts of a polymerizable feed containing a coagulated olefin having 4-6 C. atoms per molecule and a mono-ethylenically unsaturated substance in an aqueous medium containing 50 to 300 parts of water, 1 to 10 parts of an alkylated aryl polyether alcohol, 1 to 10 parts of an alkali metal salt of a rosin acid and a water-soluble salt in an amount just below that which poisons polymerization and maintaining the dispersion at between 0 DEG C. and 100 DEG C. in the presence of 0.1 to 3 parts of an oxidizing polymerization catalyst. Specified coagulated olefins are butadiene, isoprene p and 2, 3-dimethylbutadiene-1.3 which may be copolymerized with acrylonitrile, methacrylonitrile, styrene and p-methyl styrene. Specified rosin acids are tetrahydro-, dihydro,- and dehydro-abietic acids and dextro- and isodextro-pimaric acids, purified water-soluble salts are sodium sulphate, chloride and pyrophosphate, and specified catalysts are sodium, potassium and ammonium persulphates, and perborates and hydrogen and benzyl peroxides, cumene hydroperoxide and tert-butyl peroxide or hydroperoxide. Reducing agents such as dextrose (redox) may be present as may be protective colloids, e.g. casein, soybean and alpha protein. Modifiers such as mercaptan, carbon disulphide and carbon tetrachloride are optional ingredients, together with buffers such as morpholine, sodium cyanide and potassium ferricyanide and preservatives such as sodium pentachloro-phenate, anti-foam agents such as pine oil, and pigments and pigment extenders such as titanium dioxide, lithopone and mica. Cross-linking agents such as divinyl benzene can be included to give harder polymers. Short-stoppers and anti-oxidents such as hydroquinone, phenyl beta-naphthylamine, ditertiary butyl cresol, 2, 2-diphenylol propane, and hydroxylamine hydrochloride may be added to the prepared latex.

Abstract: A resinous copolymer is prepared by copolymerizing 50-70 per cent of a diolefin with 50-30 per cent mono-olefin at between 50 DEG F. and 125 DEG F. and at a pressure at least equal to the total input pressure of the reactants by the addition thereto of an anhydrous Friedel-Crafts catalyst dissolved in an inert solvent. Specified diolefins are butadiene (preferred), isoprene, dimethyl butadiene, piperylene, dimethallyl and allocymene, while diisobutylene (preferred), propylene, n- and iso-butylenes, n- or iso-pentenes, hexenes, heptenes and octenes are isoolefins mentioned. Specified catalysts are aluminium chloride, bromide, chlorobromide, aluminium chloride-aluminium alkoxide double salt, boron trifluoride, titanium chloride, zirconium chloride and the uranium chlorides and inert solvents are ethyl and methyl chlorides, carbon disulphide, ethylenedichloride and chloroform. A diluent-solvent for the copolymer, which may be the same as the catalyst solvent may also be present, and the reaction may be carried out at a pressure of from 30-50 p.s.i.g. The catalyst solution is preferably added over a period and the polymerization continued to from 60 80 per cent conversion when the supply of catalyst is discontinued and the catalyst quenched.
