Abstract

The nature of hydrogen bonding in methanol solutions of Policarbinol was investigated by the methods of Viscometry and Light scattering. The intrinsic viscosity (η) of narrow fraction of Policarbinol in methanol in presence of various amounts of hydrogen bond acceptor—sodium hydroxide (NaOH) was determined using Viscometry. It was established that the values of with addition of are passing through the extreme values due to the fact that intermolecular hydrogen bonds are broken first resulting in the decrease of, and then break in intramolecular hydrogen bonds is leading to increase of . Huggins constant reaches maximum value at complete suppression of intermolecular hydrogen bonds. Results of Light scattering show that the addition of an acceptor hydrogen bonds decreases the mean-square radii of gyration symbatically to values. The most compact size of macromolecules corresponds to minimum of values.
