Abstract

Mixtures of a major proportion of a pure isoolefin with minor proportions of a pure polyolefin are polymerized at -40 DEG to -165 DEG C. by the use of a solid or liquid Friedel-Crafts catalyst in a low-freezing inert solvent in the presence of from 0.001 to 15 per cent by weight of an organic modifying agent selected from one or more of the following classes, viz. hydrocarbons having a non-metallic substituent selected from Groups V and VI of the Periodic Table with or without halogen, C4 and higher normal olefins, C5 and higher isoolefins and aromatic hydrocarbons. Specified isoolefins are isobutylene, 2-methyl-butene-1 and 2-methyl-pentene-1 and specified polyolefins p are butadiene, isoprene, piperylene, dimethyl butadiene, myrcene and dimethallyl, the preferred polyolefins having from 4 to 14 carbon atoms per molecule. Specified groups of modifiers are the hydrocarbons, alcohols, ketones, organic acids and their esters, thioacids are their esters, amides, amines, nitrites, organic sulphides and mercaptans, ethers, sulphoxides, sulphones, sulphonates, organic sulphates, acid halides, acid anhydrides, nitro compounds, nitroso compounds, nitrates, nitrites, hydroxylamines, selenides, substituted alcohols of the type of ethylene chlorohydrin, substituted acids such as chloracetic acid, substituted phenols such as meta - chlorophenol, dicyandiamide, metallic alcoholates, sulphonamides, phenols, ureas, cyclic dinitrogen compounds such as pyrimidine and pyrazoline and acetylene. Particularly preferred modifiers are diisobutylene, ethyl ether, butene-1, butene-2, benzene, xylene, toluene, cumene, naphthalene, methyl alcohol, methyl oleate, acetaldehyde, isoamyl butyrate, amyl stearate, dodecyl mercaptan, tributylamine, Lorolamine, trimethylamine, oleic acid, sulphur dioxide, acetone and trimethylethylene. Long lists of specified modifiers are given. The products may be compounded with carbon black, stearic acid, zinc oxide, tetramethyl thiuramdisulphide, and sulphur. Specifications 525,542, 560,924, 577,350 and 589,393 are referred to.
