  The invention relates to a method for preparing linear polymers having an amide end or having a star architecture comprising an amide core, by means of a ring opening using lactide and glycolide monomers or a lactide monomer ring in the presence of a catalyst, wherein the method includes the steps of: (i) reacting the excess monomer(s) with an initiator in a solvent, said initiator being selected from among an amine and an amino alcohol, given that the initiator has at least one primary or secondary amine function; (ii) adding a catalyst, said catalyst being a non-nucleophilic base and including at least one neutral sp2 nitrogen atom; and (iii) neutralizing the reaction mixture. Said novel method is particularly advantageous in that it can be easily monitored and enables better modulation of the polymers, and thus of the properties thereof, than the methods of the prior art. The invention also relates to novel polymers that are obtainable by means of said method.

  该发明涉及一种制备具有酰胺端或具有星形结构包括酰胺核的线性聚合物的方法，通过在存在催化剂的情况下使用乳酸内酯和甘氨酸内酯单体或乳酸单体环开启的方法，其中该方法包括以下步骤：(i)将多余的单体与溶剂中的引发剂反应，所述引发剂从胺和氨基醇中选择，其中引发剂具有至少一个一次或二次胺基；(ii)添加催化剂，所述催化剂是非亲核碱，并包括至少一个中性sp2氮原子；(iii)中和反应混合物。该新方法特别有利之处在于可以轻松监控，并且比现有技术的方法更好地调制聚合物及其性质。该发明还涉及通过该方法可获得的新型聚合物。
