How good is CuAAC “click” chemistry for polymer coupling reactions?

Journal of Polymer Science Part A: Polymer Chemistry, 2017
ABSTRACT1H NMR and SEC analyses are used to investigate the overall efficiency of Copper Catalyzed Azide Alkyne Cycloaddition (CuAAC) “click” coupling reactions between alkyne‐ and azide‐terminated polymers using polystyrene as a model. Quantitative convolution modeling of the entire molecular weight distribution is applied to characterize the outcomes
