<p>Process for the preparation of a highly branched polymer by causing the terminal groups X of a precursor polymer containing monomer units Y and of which at least a proportion of whose chains each has one terminal group X which is reactive with the monomer units Y, to react with the monomer units Y, the proportion of the chains containing two terminal groups X being so small that no gel can be formed in the reaction between the monomer units Y and the terminal groups X.</p> |
