    摘要： The present invention relates to a process for the preparation of a grafted polymer wherein in a first step A) a stable nitroxyl radical is grafted onto a polymer, which step comprises heating a polymer and a nitroxyl-ether containing a group (=NO-X), wherein X is selected such, that cleavage of the O-X bond occurs and a radical X, is formed at about the melting temperature of the polymer; and in a second step B) the grafted polymer of step A) is heated in the presence of an ethylenically unsaturated monomer or oligomer to a temperature at which cleavage of the nitroxyl-polymer bond occurs and polymerization of the ethylenically unsaturated monomer or oligomer is initiated at the polymer radical; maintaining said temperature for further polymerization and afterwards cooling down the mixture to a temperature below 60° C. Further subjects are grafted thermoplastic polymers prepared by said process, the intermediate polymeric radical initiator, the use of the polymeric radical initiator and the use of NO-ethers for grafting thermoplastic polymers.
