    摘要: The invention pertains to a method of producing comb block copolymers from epoxy-functionalized nitroxylethers and further monomers by anionic polymerization followed by nitroxyl mediated controlled free radical polymerization. The block copolymer backbone has defined initiating points where radical grafting of ethylenically unsaturated monomers can take place. Further aspects of the invention are comb block copolymers obtained by this process and the use of such polymers for plastic applications.
