Abstract : The viscosities of copolymer fractions were measured in various solvents in the presence of additives which broke down intramolecular H bonds. The viscosity was found to increase significantly in m-xylene in the presence of acetic acid, while HAc had a slight influence in the case of methanol and their mixture. In the remaining systems studied, no significance of these qualities in the presence of HAc was observed.
