Abstract
Dielectric constant measurements in carbon tetrachloride and in benzene were used to obtain dipole moments of atactic poly(propylene sulfide) chains of sufficiently low molecular weight that excluded volume effects were absent. The results are in very good agreement with rotational isomeric state calculations. Comparisons with previously reported experimental results on the high molecular weight polymer confirm the existence of a significant specific solvent effect on the dipole moments.
