Solution and Solid State Behavior of Poly(N-Acetyliminoethylene)–Poly(Methacrylic Acid) Interpolymer Complexes

Abstract

A thorough comparative study of poly(N-acetyliminoethylene)-poly-(methacrylic acid) blends, corresponding synthetic complexes and template complexes was performed. The experimental data, obtained from DSC, TGA, X-ray diffraction, viscometric and turbidimetric determinations, showed the dependence of the solution and solid state properties of the studied systems, not only on their structural features but also on the adopted preparative approach. The different degrees of orientation of groups involved in interpolymer hydrogen bonding interactions yielded a higher thermal stability for template complexes as compared to the other studied polymeric materials.

The possibility of transforming the physical interpolymer bonds into chemical ones through a transamidation reaction was evidenced.
