Abstract The invention relates to a process for the anionic polymerisation and copolymerisation of vinyl, dienic and heterocyclic monomers, According to the invention, the process consists in carrying out the reaction in the presence of an initiator consisting of a molecular combination of an alkali metal amide and the salt of the same alkali metal with at least one hydroxylic compound and in the absence of solvent, The initiator can be prepared by intimately mixing its consti- tuents or in the presence of a solvent of low polarity which is subsequently evaporated off, or in situ in the monomer. Application to the synthesis of special or widely used polymers and copolymers.
