  The instant invention relates to a process for the preparation of grafted polymers wherein in a first step A) a oligomer or polymer is prepared by controlled radical polymerization in the presence of a stable free nitroxyl radical or a nitroxylether to obtain a nitroxyl terminated oligomer or polymer and in a second step B) the nitroxyl terminated oligomer or polymer is mixed and reacted with a thermoplastic or elastomeric polymer or copolymer in its molten state at a temperature at which cleavage of the nitroxyl-polymer/oligomer bond occurs, whereby the nitroxyl terminated oligomer or polymer is grafted onto the thermoplastic or elastomeric polymer. A further subject of the present invention is a grafted polymer prepared by said process.

  本发明涉及一种接枝聚合物的制备工艺，其中第一步 A) 在稳定的游离亚硝基自由基或亚硝基醚存在下，通过受控自由基聚合制备低聚物或聚合物，以获得亚硝基封端的低聚物或聚合物；第二步 B) 将亚硝基封端的低聚物或聚合物与热塑性或弹性聚合物或共聚物混合，并在熔融状态下与之反应，反应温度为亚硝基-聚合物/低聚物键发生裂解的温度。聚合物/异构体键发生裂解、从而将硝基末端低聚物或聚合物接枝到热塑性或弹性聚合物上。本发明的另一个主题是通过上述工艺制备接枝聚合物。
