Resumo

Abstract The cohesive energy density of cis ‐polybutadiene has been estimated from viscosity and swelling measurements. The method was extended to turbidiometric titrations with a nonsolvent and the results were found to be very consistent. The average value of the solubility parameter (under‐root of cohesive energy density) was observed to lie between 8.5 to 8.6 (cal/ml) 1/2 . The F LORY ‐H UGGINS solvent‐polymer interaction parameter, determined from H UMMEL 'S method, was found to be 0.3889.
