Vi. Karmanov et Vv. Tereshatov, DETERMINATION OF THE CONTENT OF ASSOCIATE D URETHANE GROUPS IN CONCENTRATED POLY(BUTADIENEURETHANE) SOLUTIONS, Vysokomolekularnye soedinenia. Seria A, 39(10), 1997, pp. 1697-1700
The formation of hydrogen bonds in concentrated poly(butadieneurethane
) solutions in carbon tetrachloride, pentadecane, transformer oil, and
dioctyl sebacate, that are used as plasticizers, was studied by the I
R spectroscopy. The content of associated urethane groups was determin
ed at various concentrations of a low-molecular-weight component. The
results obtained correlate with variations in the mechanical propertie
s of elastomers on their swelling in polar or weakly polar liquids and
can be used for the prediction of these properties.
