摘要: The invention provides a process for the living free radical addition polymerization of one or more ethylenically unsaturated monomers using at least one free-radical polymerization initiator and in the presence of one or more stable N-oxyl radicals, wherein at least one stable N-oxyl radical has polymerizable double bonds. The invention additionally provides polymers obtainable by this process, having a polydispersity index PDI of from 1.0 to 1.8, and provides for the use of stable N-oxyl radicals having polymerizable double bonds in the living free radical addition polymerization of one or more different ethylenically unsaturated monomers.
