Abstract

An aqueous emulsion of "natural rubber" and at least one "vinyl compound" is polymerized in the presence of a dissolved salt of perdisulphuric acid and a dispersing agent consisting of an alkali metal salt of a longchain alkyl acid sulphate or sulphonate, containing 12-18 carbons whose activity is unaffected at pH values of 3-5. Definitions of "natural rubber" and "vinyl compound" are given; specified materials include rubber latex (hevea brasiliensis) balata and guttapercha; and styrene, vinyl esters, ketones and ethers, acrylic and methacrylic esters and nitriles, and asymmetrical dichlorethylene. Preferred dispersing agents are sodium cetyl sulphate and the sodium salt of sulphonated paraffin oil; lists of other suitable dispersing agents are given. Examples are given of the preparation of copolymers of rubber and (1) methyl methacrylate; (2) styrene; (3) acrylonitrile; (4) vinyl acetate; (5) butyl methacrylate; (6) asymmetrical dichlorethylene; and (7) 2-nitro-2-methyl propyl methacrylate.ALSO:An aqueous emulsion of "natural rubber" and at least one "vinyl compound" is polymerized in the presence of a dissolved salt of perdisulphuric acid and a dispersing agent consisting of an alkali metal salt of a long-chain alkyl acid sulphate or sulphonate containing 12-18 carbons whose activity is unaffected at pH values of 3-5.
