New copolymers with heterocyclic pendant groups obtained from PVC using microwave-assisted process

We report the synthesis of new copolymers from poly(vinyl chloride) (PVC) with 1,2,4-triazol-5-yl-sulfanyl pendant groups (PVCT) by nucleophilic substitution using microwave energetic sources. By comparing the synthesis of PVCT between microwave and thermal conditions, it was found that the use of m...
