On heating a disecondary aromatic diol with an alkanol in an aromatic solvent in the presence of an acid catalyst, condensation telomerization takes place with the formation of oligomeric ethers, alcoholysis of which and condensation of hydroxylated intermediate products gives dialkyl ethers of the diol, followed by cleavage of these ethers to give vinyl- and divinylaromatic compounds, and cationic polyaddition of these monomers to give straight-chain unsaturated oligomers, giving mixtures of vinylaromatic compounds and unsaturated straight-chain oligomers. The rate of cleavage of dialkoxy-derivatives of the aromatic diol decreases as the reaction progresses as a result of the increasing concentration of the liberated alkanol, which modifies the activity of the catalyst.
