Lc. Cesteros et al., FORMATION OF INTERPOLYMER COMPLEXES BETWEEN POLY(MONOETHYL ITACONATE)AND POLY(N-VINYL-2-PYRROLIDONE), Polymer international, 34(1), 1994, pp. 97-103
This paper reports on the interpolymer complex formation and polymer b
lends between poly(monoethyl itaconate) (PMEI) and poly(N-vinyl-2-pyrr
olidone) (PVP). The formation of the interpolymer complex was found to
depend upon the solvent medium. Stoichiometry of the complexes prepar
ed from methanol solutions, as calculated from elemental analysis, is
close to 1:1. Specific interactions bf PMEI/PVP complexes and blends o
f these polymers have been characterized by FTIR. Strong hydrogen bond
ing for complexes and blends has been found. A calorimetric study of t
he complexes and blends has been performed over a wide temperature ran
ge.
