Notes:
Polymer blends of an amorphous polyamide with poly(2vinyl pyridine) (P2VP) are presented. Differential scanning calorimetry results suggest that the system exists as a single phase material as evidenced by a single glass transition temperature. However, as illustrated by light scattering studies, this miscible binary mixture possesses a relatively low, lower critical solution temperature (LCST). Fourier transform infrared (FTIR) spectroscopic investigations indicate that the interactions occur in the blend between the N—H group of the polyamide and the —N: atom of P2VP and that the strength of the Interactions between the components is nearly identical to that occurring in the self-association of the pure amorphous polyamide. Additionally, by monitoring the concentration of “free” carbonyl groups, a quantitative measure of the number of interactions occurring in the blend is obtained.
