Abstract

Butadiene telomers are prepared by telomerizing butadiene in the presence of at least one free-radical forming compound as catalyst at at least 100 DEG C. in at least one chan transferring solvent, the butadiene and catalyst being introduced into the reaction vessel initially containing only the solvent at a desired temperature and the rate of introduction of the butadiene being the same as its rate of consumption in the reaction. The free radical forming compound is e.g. an organic peroxide such as ditertiary butyl peroxide, dilauroyl peroxide, dibenzoyl peroxide, cumene hydroperoxide and tertiary butyl hydroperoxide, or an azo compound e.g. azo bisisobutyronitrile. The solvent may be a saturated aliphatic hydrocarbon containing a tertiary carbon atom, a halogenated aliphatic hydrocarbon, a saturated aliphatic primary or secondary alcohol or a ketone. The preferred solvents are aromatic hydrocarbons substituted by aliphatic groups containing at least one labile hydrogen atom, particularly those of general formula wherein R1 represents a benzene nucleus having 5-n hydrogen atoms, R2 and R3 are hydrogen atoms or alkyl, aryl or phenyl alkyl groups, X is a hydrogen or halogen atom or a nitro or hydroxyalkyl group and n is an integer in the range 1 to 4. Cumene and xylene are specified examples. The telomers produced have a molecular weight of 300 to 3000, an iodine number of 280 to 450 and about 65% of their double bonds are trans and about 25% are in the form of vinyl groups. In the examples the catalyst used is ditertiary butyl peroxide and the solvents are cumene, toluene, xylenes and n-butanol. The telomers can be used for preparing coatings, which can be hardened by oxidation or free radicals, and as plasticizers.
