| Research Abstract |
Long-branched polycondensates were prepared by self-polycondensastion of branched macromonomers. Inherent viscosity of the branched poly(ether sulfone)s increased with increasing the molecular weight of the macromonomers. The radius of gyrations of the branched poly(L-lactide)s in HFIP were much smaller than those of the linear PLLA with the corresponding weight-average molecular weight. It is experimentally revealed that the introduction of branching strongly affects the molecular architecture of the resulting polymers.
