Abstract

Procédé pour la polymérisation de composés possédant un système de doubles liaisons conjuguées. Le perfectionnement apporté à ce procédé est dû au fait qu'on fait réagir le monomère en présence d'un catalyseur qui est le produit de l'interaction de divers dérivés éthyléniques substitués avec un métal alcalin. Le métal alcalin est de preférence du sodium et le substrat est choisi parmi le stilbène, les diphényléthylènes, triphényléthylènes et tétraphényléthylènes. Ce procédé permet de polymériser des composés possédant un système de doubles liaisons conjuguées.Process for the polymerization of compounds having a system of conjugated double bonds. The improvement brought to this process is due to the fact that the monomer is reacted in the presence of a catalyst which is the product of the interaction of various ethylene derivatives substituted with an alkali metal. The alkali metal is preferably sodium and the substrate is chosen from stilbene, diphenylethylenes, triphenylethylenes and tetraphenylethylenes. This process makes it possible to polymerize compounds having a system of conjugated double bonds.
