  A one-pot process for the preparation of alkoxyamines conforming to formulae (I) or (II), preferably (I) 1 is disclosed. The process entails (1) reacting of an oxidizing agent (A) with a sterically hindered secondary amine of the general formula (III), 2 in a water-containing medium to form a reaction product and an aqueous phase, (2) removing of the aqueous phase, and (3) (adding to the reaction product a free-radical initiator (B) under conditions that promote the decomposition of the initiator to generate free radicals. Also disclosed is a process for polymerizing monomers, the process using the alkoxyamine prepared by the inventive process.

  披露了一种用于制备符合公式(I)或(II)，最好是(I)的烷氧基胺的一锅法工艺。该工艺包括：(1)使氧化剂(A)与具有空间位阻的二级胺反应，该二级胺的通用公式为(III)，在水含介质中形成反应产物和水相，(2)移除水相，以及(3)在促进分解引发剂以产生自由基的条件下，向反应产物中添加自由基引发剂(B)。还披露了一种用于聚合单体的工艺，该工艺使用由发明工艺制备的烷氧基胺。

  The present invention is a multistage process for the preparation of a co)polymer composition. Said process comprises the steps of: i) polymerizing in a first stage a reaction mixture comprising one or more monomer with optionally a rubber, a comonomer, a polymerization initiator, a chain transfer agent, a decomposition catalyst and/or a solvent, in the presence of one or more stable free radical precursor which provides a stable free radical during the polymerization process and/or one or more stable free radical such that the polymerization proceeds via a mediated free radical polymerization mechanism until a partial conversion of monomer(s) to (co)polymer is obtained and ii) polymerizing in a second stage the partially converted reaction mixture under reaction conditions that proceed via a free radical polymerization mechanism to obtain a further degree of conversion of monomer(s) to (co)polymer.
