Abstract
Permeability and positron annihilation measurements were carried out on PTM SP membranes, in the pristine structure, as well as in the modified polymer after chlorination. It is found that permeability decreases in the chlorin ated films; this can be correlated to the microscopic free volume decrease as probed by positronium. Effect of ageing was also investigated.
