Abstract

A polymerization catalyst for 1,3-butadiene is made by reacting a titanium iodide, an aluminium alkyl, and a carboxylic acid and/or a beta-dicarbonyl compound in the presence of an alkyl halide. The titanium iodide may be TiI2, TiI3, or TiI4, and the aluminium compound aluminium triethyl, triisobutyl, or trihexyl. Specified acids and carbonyl compounds are acetic acid, trichloro- or trimethyl acetic acid, oleic acid, hexahydrobenzoic acid, stearic acid, phthalic acid, adipic acid, acetylacetone, benzoylacetone, cyclohexandione - 1:3, ortho - hydroxybenzaldehyde, ethyl acetoacetate, and benzoyl acetic ester. The alkyl halide may be methyl, isopropyl, or tert.-butyl iodide, cyclohexyl bromide, benzyl chloride, benzal chloride, butyl bromide, iodoform, or 1-chloro-4-iodobutane. The catalyst is preferably preformed and the polymerization effected in a hydrocarbon solvent or diluent. The reaction is terminated by adding N: N1-diphenyl-para-phenylene diamine and rosin acid, or ethanolamine, isopropanol, and methylene-di-2: 21-dihydroxy-3: 31 - di - tert. - butyl - 5: 51 - dimethylbenzene. The butadiene polymers are vulcanized by conventional techniques.
