TAD Click Chemistry on Aliphatic Polycarbonates: A First Step Toward Tailor-Made Materials.

For the first time, the effectiveness of triazolinedione (TAD) click chemistry onto aliphatic polycarbonates (APC) is demonstrated. Statistic copolymers carrying click-reactive conjugated diene (in a ratio of 10%) are synthesized via organocatalyzed ring-opening polymerization. The highly efficient click reaction of TADs carrying simple butyl and phenyl functions are confirmed by 1 H-NMR and DSC. Network formation using a bivalent TAD is also performed and simply characterized by DSC. This post-polymerization functionalization of biocompatible and biodegradable APC pave the way to easy and versatile "on-demand" materials design.
