A process for polymerizing unsaturated monomers is disclosed. The process comprises polymerizing, in the presence of a late transition metal catalyst (LTMC), a variety of unsaturated monomers which are traditionally, some of which are exclusively, made by free radical polymerizations. The LTMC polymerization provides the polymer with improved properties such as no free radical residue and narrow molecular weight distribution.
L'invention concerne un procédé de polymérisation de monomères non saturés : polymérisation, en présence de catalyseur de métal de transition tardive (LTMC), d'une série de monomères non saturés généralement issus de polymérisation à radicaux libres, certains d'ailleurs exclusivement. Une telle polymérisation donne au polymère des propriétés améliorées du type absence de résidus de radicaux libres et distribution de masse moléculaire étroite.
