    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.

    摘要: The present invention relates to a process for increasing the molecular weight and for the modification of polycondensates, to the use of an additive blend effecting the increase in molecular weight without imparting color to the polycondensates as well as to the polycondensates obtainable by that process. The additive blend contains at least one bis-acyllactam, at least one phosphite, phosphinate or phosphonate; or at least one benzofuran-2-one type compound or at least one phosphite, phosphinate or phosphonate and one benzofuran-2-one type compound.
