Abstract: The invention relates to a method for the living free-radical polymerization of one or more ethylenically unsaturated monomers by means of a free-radical polymerization initiator and in the presence of a stable N-oxyl radical. As free-radical polymerization initiator a combination of at least two different initiators having different dissociation constants kD is used.

Abstract: The invention relates to a method for the living free-radical polymerization of one or more ethylenically unsaturated monomers by means of at least one free-radical polymerization initiator and in the presence of one or more stable N-oxyl radicals, at least one of which has polymerizable double bonds. The invention also relates to polymers which are obtained according to this method and have a polydispersity index (PDI) of between 1.0 and 1.8, and to the use of stable N-oxyl radicals with polymerizable double bonds in the living free-radical polymerization of one or more different ethylenically unsaturated monomers.
