Abstract

The possibility of convection in velocity sedimentation studies on pressure dependent associating systems is known both experimentally and theoretically. We present accurate numerical solutions to the Lamm equation to illustrate this phenomenon for monomer–polymer systems. An approximate theory based on the absence of diffusion is then developed to predict the onset of convection. Comparison of the theory with the numerical solutions shows it to be quite accurate.

The effect of pressure on gas permeability of a rubbery polymer, 1,2-polybutadiene, is investigated for 15 gases with various molecular sizes and solubilities in the ranges of pressure up to 110 atm at 25°C. The permeability for slightly soluble gases (He, Ne, Hz, Nz, 02, and Ar) decreases with incr
