| Abstract: | The dependence of the specific viscosity of polyepichlorohydrin solutions in various solvents on the concentration of solutions was investigated. It was shown that there is only a little difference between specific viscosity measured in various solvents at the same concentration. Solubility diagrams for polyepichlorohydrin were made using both Hansen and Lieberman method and some properties (specific viscosity, evaporation rate and solvent retention in adhesive films) of solutions were plotted against the composition of solvent mixtures. A definite dependence of the specific viscosity on the position of solvent mixture in solubility diagrams was found. This behaviour is discussed in terms of intermolecular attractions. |
