Abstract: 1,149,745. Copolymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 26 Aug., 1966 [28 Aug. 1965], No. 38301/66. Heading C3P. Copolymers containing chlorine may be prepared by copolymerizing a 1,3-diene with 2- chloroprene under conventional polymerization conditions. The diene may be butadiene or isoprene, and other monoolefinically unsaturated compounds, e.g. vinyl esters, ethers and ketones, unsaturated acids and esters, amides, nitriles and anhydrides thereof, and vinyl aromatic and heterocyclic compounds, may also be copolymerized. Polymerization may be effected in the presence of Ziegler catalysts, peroxides and azo compounds, redox systems, transition metal chelates and mixtures of cobalt and nickel carbonyls with aluminium halides and complexing agents or alkyl aluminium compounds; in organic liquid media or in aqueous emulsion or suspension in the presence of conventional emulsifiers and suspending agents. Extensive lists of comonomers, catalysts and conventional media and agents are given and examples describe the copolymerization of (1) butadiene and (2) isoprene with 2-chloropropene in n-hexane and paraffin oil in the presence of cobalt acetylacetonate and diethyl aluminium chloride, of (3) butadiene and 2-chloropropene in aqueous dispersion in the presence of a sodium paraffin sulphonate and gold acetylacetonate, and of (4) butadiene, 2-chloropropene, styrene and acrylonitrile in aqueous dispersion in the presence of a sodium paraffin sulphonate and potassium persulphate.
