Webreactions as well as polymerizations in aqueous media have been extensively investigated, and so far, there has been a massive amount of reporting about polymerizations in water. However, reports about click polymerization in water have been rare. Herein, click polymerization of activated alkyne and aromatic amine in aqueous media is developed. WebA simple and an efficient approach has been developed for the synthesis of polyesters containing pendant thiolactone units. For this purpose, polyester P1 possessing electron deficient triple bonds in the main backbone was prepared, and subsequently reacted with benzyl-azide and thiolactone-azide (TLa-N 3) at a mole ratio of 2:1 (per alkyne), through …
