Abstract
THE polymerization of isobutene and the dimerization of di-isobutene are both catalysed by Friedel–Crafts catalysts. Earlier work on these reactions, has led to the conclusion that a third component, other than the Friedel–Crafts catalyst and the monomer, is necessary for an appreciable reactionrate to occur; and it has been shown, in particular, that the rapid polymerization of isobutene in the gas phase, using boron trifluoride as catalyst, does not occur if these reactants are pure, but does occur if a trace of water is present1.
