Anionic polymerisation of vinyl, diene or heterocyclic monomer - in presence of anionic initiator and macro-heterocyclic complexing agent

摘要

Anionic (co)polymerisation, as described in parent patent, takes place in the presence of monomer or comonomers, an anionic initiator, and a macroheterocyclic complexing agent. Pref., a soln. of the initiator is placed in a polymerisation reactor, the solvent is evaporated, and a soln. of the macroheterocyclic complexing agent in the monomer is then introduced over the dry initiator. The process gives high yields of polymer. Sepn. of the polymer is facilitated by the absence of a solvent medium.
