Web20 Jan 2016 · 4.3 Post-polymer Modification via Azide Alkine Cycloaddition Another successful method to obtain functionalized polymers is represented by cycloaddition reaction and among them the catalyzed azide/alkine, so called “click” reaction, that is a variation of Huisgen 1,3-dipolar cycloaddition between terminal acetylenes and azides. WebPost-polymerization modification, also known as polymer-analogous modification, is an alternative approach to overcome these limitations. It is based on the polymerization of monomers with functional groups that are inert towards the polymerization conditions but allow a quantitative conversion in a subsequent reaction step yielding a broad range of …
