Permeability of Organic Solvents through Polyurethane Membranes

摘要

The values of coefficients of permeability of organic solvents through polyurethane membrane Vibrathane B-600 can be generalized by means of multiparameter linear equations. Polarity of solvents increases their permeability whereas increase in molar volume of solvents, their self-association and ability to electrophilic solvation of amide structures of membrane reduce it.
