A method is provided for the direct synthesis of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cuano, carbonylamino or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or of tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.
本发明提供了一种直接合成新型聚合物材料的方法,该材料具有理想的含氮官能团,如末端叠氮基、氨基、羰基氨基或硫代羰基氨基。聚合和官能化基本上是同时进行的。聚合开始时,官能化所需的所有反应物都已存在。含氮官能团是作为分子的一部分提供的,该分子具有释放基,释放基最好是共振稳定的或叔烷基类型的,其作用是帮助含氮物质作为离去基团发挥作用。
