Notes:
The partial specific compressibilities of polystyrene at infinite dilution in such solvents as methyl ethyl ketone, toluene, dioxane, and a mixture of methanol and toluene were determined by ultrasonic velocity measurements and were compared with the intrinsic viscosities. The limiting partial specific compressibility decreased with decreasing solvent power. The variation of this quantity was ascribed to the increase in the segment-segment contacts on the basis of a macroscopic model. The limiting partial specific compressibility is a measure of the compactness of the polymer molecule.
