| description | 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 substituent on the phosphorous atom.
L'invention concerne un nouveau procédé servant à préparer des polymères, de préférence, des polymères et des copolymères de méthacrylate présentant une répartition limitée de poids moléculaire, ce qui consiste à effectuer une polymérisation anionique sans métal en présence d'un cation de phosphonium contenant au moins un noyau aromatique annelé en tant que substituant sur l'atome de phosphore. |
