Abstract

: The present invention is directed to a method for polymerizating a compound containing at least one non-aromatic system of conjugated carbon-carbon double bonds, which romprises contacting the monomer with, as sole catalyst, a compound produced by the reaction in an ethereal solvent of equimolar quantities of sodium and an ethylenic compound having the formula : <IMG> wherein each of R1, R2, R3 and R4, which can be the same or different, is a hydrogen atom or an alkyl, aryl, aralkyl or alkaryl radical, with the proviso that at least one of R1, R2, R3 and R4 is selected from aryl, aralkyl and alkaryl radicals.
