Click polymerization [PDF]

open access: yesChemical Society Reviews, 2010
The development of new polymerization reactions is of critical importance to macromolecule science. In this critical review, we summarize the research efforts to incubate alkyne-azide click reactions into a versatile polymerization technique for the synthesis of poly(triazole)s (PTAs) with linear and hyperbranched structures.
