Curve Fitting Analysis

In this paper we have performed a spectroscopic study of the polymer–polymer complexes and polymer blends formed by mixing poly-acids [a series of poly(mono- n-alkyl itaconates)], and polybases [poly(2-vinyl pyridine) and poly(4-vinyl pyridine)]. The poly(mono- n-alkyl itaconates) are proton donors and the poly(vinyl pyridines) are good proton-acceptor polymers. Therefore, these pairs of polymers can interact via hydrogen bonding under given conditions. The obtained spectroscopic results point out the existence of hydrogen bonding in the studied systems. In addition to the qualitative hydrogen-bonding evidence observed in the hydroxyl and carbonyl stretching region, the curve-fitting analysis of the characteristic modes of the pyridine groups allows a quantitative study of the specific interactions to be performed.
