Abstract:

A method of calculating critical surface tensions of polymers from their chemical structure only is described. For a set of 28 polymers, the standard deviation of the differences between calculated and observed values is 5.0 dynescm with a mean difference of 3.5 dynescm. Using additive constants for calculating molar volumes, surface tensions of 24 various liquids are predicted from the parachor. The standard deviation of the differences between calculated and observed surface tensions is 4.5 dynescm and the mean error is 2.9 dynescm. Cohesive energy is found to be a function of the reciprocal of molar volume. Author
