Abstract

Styrene is copolymerized with a polyolefin having six or more carbon atoms at a temperature below 0 DEG C. in the presence of a solution of a Friedel-Crafts halide catalyst. Polyolefins specified are piperylene; 2,3-dimethyl-butadiene-1,3; 1,4-dimethyl-butadiene-1 : 3; heptadiene-2,4; heptadiene-1,3; 2-methyl-3-ethylbutadiene; 2-methyl-pentadiene; di-isobutenyl; 2-methyl-pentadiene-1,5; 2-methyl-3-butyl-butadiene - 1,3; 2,3 - diethyl - butadiene - 1,3; myrcene, alloocimene, cyclo-pentadiene and the dimer thereof and mixtures of any of these. Catalysts specified are aluminium chloride, boron fluoride, AlBr3; AlBr2Cl; AlCl2Br; Al2Br5Cl, TiCl4; TiCl4-AlCl3; TiCl4-Al(OC2 H5)3; AlCl3, AlCl2OH; AlBr3, AlBr2OH; AlBr2Cl, AlOCl; AlBrCl2-AlOBr; TiCl4, AlCl2OH; TiOCl2TiCl4; AlBr3Br2CS2; AlBr3, Br4, CS2; BF3-isopropyl alcohol complex, BF3 in ethylene and activated BF3 in ethylene, and AlCl3-isoprene complex. Solvents specified are methyl and ethyl chlorides, alone or with butane and propane, and carbon disulphide. Ethylene ethane, or carbon dioxide may be used as internal or external refrigerants. After polymerization the residual catalyst may be hydrolysed by ethyl or methyl alcohol, water or caustic soda or mixtures of these. Acetone and isopropyl alcohol may be used to deposit the copolymer. The products may be added to petrol naphtha, benzene, toluene, paracymene, turpentine, linseed oil and drying, semi-drying or non-drying oils, pigments, dry earths, natural or synthetic rubbers, e.g. butyl rubbers, styrene - butadiene and butadiene-acrylonitrile copolymers, and low temperature isobutylene-isoprene copolymers, paraffin wax, petrolatum, vegetable waxes, asphalt, coumarone-indene, styrene-isoprene, polybutadiene or dimer acid-ethylene diamine resins, heavy mineral oil, carbon, clay, sulphur, zinc stearate, and anti-oxidants, polyisobutylene, gum rubber, polystyrene, polythene and polydichlorostyrene. Films and extruded forms may be made. Curing may be effected with zinc oxide, stearic acid, sulphur, carbon and usual accelerators.
