METHOD FOR PREPARING (CO)POLYMERS BY METAL-FREE ANIONIC POLYMERIZATION IN THE PRESENCE OF A PHOSPHONIUM CATION CONTAINING AT LEAST ONE ANNELLATED AROMATIC RING

The present invention concerns a novel method for preparing polymers (preferably (meth)acrylate polymers and copolymers) having a narrow molecular weight distribution by metal-free anionic polymerization in the presence of a phosphonium cation containing at least one annellated aromatic ring as subs...
