INFRARED STUDY OF THE INTERACTIONS BETWEEN POLY(VINYL PYRIDINES) AND POLY(MONO-N-ALKYL ITACONATES)

In this paper we have performed a spectroscopic study of the polymer-p oly mer complexes and polymer blends formed by mixing polyacids [a ser ies of poly(mono-n-alkyl itaconates)], and polybases [poly(2-vinyl pyr idine) and poly(4-vinyl pyridine)]. The poly(mono-n-alkyl itaconates) are proton donors and the poly(vinyl pyridines) are good proton-accept or polymers, Therefore, these pairs of polymers can interact via hydro gen bonding under given conditions, The obtained spectroscopic results point out the existence of hydrogen bonding in the studied systems. I n addition to the qualitative hydrogen-bonding evidence observed in th e hydroxyl and carbonyl stretching region, the curve-fitting analysis of the characteristic modes of the pyridine groups allows a quantitati ve study of the specific interactions to be performed.
