Abstract
Polymerization process, for transposing to polymers endowed with a very regular structure, of esters containing at least two unsaturated conjugated double bonds and which are included in the general formula (1) RI-CH = CH-CH = CH-COORII (1) wherein RI and RII, equal or different from each other, represent a radical selected from the group consisting of alkyl, cycloalkyl, aryl and aralkyl, optionally substituted, containing from 1 to 16 carbon atoms, characterized in that the polymerization is carried out at a temperature between +100 and -120º C, in the presence of a catalyst comprising a compound of a metal belonging to the first group of the Periodic System.
