- W4229509993 abstract "The formation of complexes between poly(N-vinyl-2-pyrrolidone) (PVP) and novolac resin in various solvents was studied. Interpolymer complexes were formed in methanol, ethanol, 2-butanone, cyclohexanone and N,N-dimethylformamide (DMF). However, only polymer blends were obtained in N-methyl-2-pyrrolidone. The nature of the solvent has a profound influence on the degree of interpolymer association. The formation of 1/1 and 2/1 ([novolac]/[PVP]) interpolymer complexes in DMF solution was shown by measurements of reduced viscosity, conductivity and clear point. Differential scanning calorimetry revealed the single-phase nature of both the blends and the complexes of uncured novolac/PVP. The complexes had higher glass transition temperatures than those of the blends with the same composition, and the strength of the interactions between the components in the complex is much higher than that in the blend. The driving force in the formation of the interpolymer complexes between novolac and PVP is the hydrogen-bonding interaction between the hydroxyl of the novolac and the proton-accepting groups of PVP. Both the blends and the complexes were cured with 15 wt% hexamethylenetetramine relative to novolac content. The cured novolac/PVP blends were only partially miscible, but significant amounts of complex still existed in the cured complexes. Fourier transfer infrared spectroscopy revealed that the interaction between the components was rather strong for both the uncured and cured blends." @default.
