Patent

CA 2494682

The instant invention pertains to polymeric alkoxyamines, which are prepared by atom transfer radical addition polymerization (ATRA). Further aspects of the invention are a process for their preparation and their use as light stabilizers, flame retardants and polymerization regulators/initiators in controlled radical polymerization processes. Yet another aspect of the invention are novel monomeric intermediate alkoxyamines, which are also useful as polymerization regulators/initiators.

La présente invention concerne des alcoxyamines polymériques préparées par polymérisation par addition radicalaire avec transfert d'atomes (ATRA). D'autres aspects de l'invention concernent une méthode de préparation et d'utilisation des alcoxyamines polymériques comme stabilisants UV, ignifugeants ou régulateurs/initiateurs de polymérisation, dans des processus de polymérisation radicalaire contrôlée. Dans un autre aspect de l'invention, on décrit de nouvelles alcoxyamines intermédiaires monomériques, utiles comme régulateurs/initiateurs de polymérisation.
