Poly(amide-triazole)s obtained by regioselective, microwave-assisted click polymerization of bio-based monomers
The Cu(I)-catalyzed, microwave-assisted click polymerization of bio-based α-azide-ω-alkyne monomers afforded, with high regioselectivity, stereoregular poly(amide-triazole)s. The monomers were prepared starting from d-glucono-1,5-lactone as a renewable resource. The synthetic route involves the sele...
