Fibre Chemistry Aims and scope

The viscosity characteristics of dilute DMSO solutions of pure polymers fluoroplast-42V and chlorinated polyvinylchloride (CPVC) and their mixtures in various ratios were determined in order to facilitate further processing of such polymer mixtures by capillaryless electroforming. The more viscous F-containing component had a decisive influence on the properties of the dilute solutions. The additive intrinsic viscosity of the mixtures was always less than that of the pure fluoroplast but greater than that of pure CPVC. The solubility parameters of the used solvents and polymers were calculated a priori by the Small—van Krevelen method with subsequent calculation of the heat of mixing equation constant for the polymer and solvent.
