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
