Telomers are prepared by subjecting aliphatic mono-olefines and a substance YZ to elevated temperature and pressure in the presence of an ethylene polymerization catalyst. The substance YZ is defined as being free from aliphatic carbon-carbon unsaturation and capable of forming monovalent fragments Y and Z, one of which is an inorganic acid radicle and the other is either an inorganic acid radicle or a radicle containing carbon and which is (a) a halogen, e.g. chlorine, bromine and iodine; (b) a halogen containing carbon compound, e.g. chloriodoform, a -brompropionic acid, propyl trichloracetate, chloracetic anhydride, chlorpropionaldehyde, ethylene bromhydrin, glycerol a -monochlorhydrin, monochlormethyl ether, methyl chloride and chloracetyl chloride; (c) or compounds containing halogen in combination with an inorganic acid radicle, e.g. cyanogen chloride and bromide; (d) a sulphur halide, e.g. benzene sulphonyl chloride and sulphuryl chloride; (e) cyanogen; or (f) an ester of an inorganic acid, e.g. triethyl borate, tetraethyl silicate, tributyl phosphate and methyl sulphate. Suitable catalysts are oxygen, hydrogen, acetyl, benzoyl, diethyl and tetrahydronaphthalene peroxides, alkali ammonium persulphates, perborates and percarbonates, tetraethyl and tetraphenyl lead, ultra-violet light especially in the presence of photosensitizers such as mercury, alkyl iodides, benzoin and acetone, di-, tri-methylamine oxides dibenzoyl hydrazine, hydrazine hydrochloride and sebacate and hexachloroethane water solvents, e.g. isooctane, cyclohexane, benzene and dioxane, surface active agents, e.g. sodium acetoxyoctadecyl sulphate, buffers, and substances capable of forming interpolymers with olefines, e.g. vinyl compounds and unsaturated acids, esters and ketones may be present. Examples describe the telomerization of ethylene and carbon tetrachloride (1 to 5); chloroform (6 to 7); methylene chloroiodide (8); chloral hydrate (9); 1,1,1-trichloroethane (10); ethyl dichloroacetate (11); dichloroacetic acid (12); hexachloroethane (13); tetra- and pentra-chloroethylbenzenes (14); hexachlorobenzene (15); trichlorofluoromethane (16); dimethyl sulphate (17); ethyl orthosilicate (18); sulphuryl chloride (19); ethyl iodide (20); a ,a 1-dichloro-dimethyl ether (25); isobutylene and carbon tetrachloride (21); ethylene carbon tetrachloride and n-octene-1 (22), styrene (23); and vinyl chloride (24). The products may contain pure compounds, e.g. of the type Cl(CH2.CH2)nCCl3, where n is an integer. They may be used as solvents, heat transfer media, plasticisers, wax substitutes, coating materials and as additions to lubricating oils.
