The rheological behaviors of hyperbranched polymers are complex and still not well understood.The melt rheology of a series of epoxide-terminated hyperbranched polyether (EHBPEs) of different molecular weight (Mw) and different structures, which were synthesized from A2+B3 polycondensation by varying A2 and reaction time, were investigated.The variation of rheological behaviors as functions of backbone structure, Mw, temperature, angular frequency and shear rate were reported.
