Jl. Velada et al., INFRARED STUDY OF THE INTERACTIONS BETWEEN POLY(VINYL PYRIDINES) AND POLY(MONO-N-ALKYL ITACONATES), Applied spectroscopy, 50(7), 1996, pp. 893-899
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.
