摘要
A new synthetic route to introduce thermo-responsive grafts onto dextrans was developed so that changing synthetic conditions can easily control the structures of graft copolymers such as graft length and number. The resulting method involves the synthesis of semitelechelic poly(NIPAAM-co-DMAAm)s with a hydrazide end-group, and coupling reaction with p-nitrophenyl chloroformate-activated dextran. Dextran graft copolymers exhibited an anomalous enzymatic degradation with temperature change.
