Abstract

The synthesis and physical properties study of poly(etherimide) AB/AB₂/A' copolymer series was carried out. By varying the ratio of AB and AB₂ monomers, and terminating with the appropriate amount of A' monomer, copolymers were synthesized with constant elemental composition and geometries ranging from hyperbranched (x_AB = 0) to linear (x_AB = 1). The differences in molecular architecture due to changes in monomer ratios affected the properties of the copolymers. The properties of PEI AB/AB₂/A' copolymers exhibited the same dependence on x_AB copolymers, indicating that variations in elemental composition have a negligible effect on the observed rheological property trends with x_AB.
