Hydrodynamic and conformation characteristics of polyimidoamide macromolecules in solution

Abstract Diffusion, sedimentation, viscosity, and birefringence in solution have been used to study polyimodoamides (PIA) produced from imido acid dichlorodes. These were shown to possess a narrow MWD ( M z / M w =1·1–1·3). The Kuhn segment consists of 2·5 monomer units and the anisotropy of the latter ( a ∥ − a ∼ ) = 250 × 10 −25 cm 3 .
