Thermodynamic and electrochemical and spectral studies of some multicomponent complexes involving polyelectrolytes and non ionic homopolymers

Mamta Chhabra Sharma, Sandeep K.Sharma

Some multi component inter polymer complexes or polymer blends have been prepared by incorporating some polymers (e.g., PVP, PEO, PVAetc.) on the poly (methacrylic acid) (PMA) chains. Stability constants and related thermodynamic parameters (e.g., H0, S0) for the systems at different temperatures were determined. Interpretations have been sought in terms of the various proportions of the component polymers and hence the secondary binding forces associated with them. A closed chain mechanism has been proposed on the basis of the experimental findings. further confirmation has been provided by spectral and electrochemical studies.
