Abstract
A radiotracer based method for the determination of the rate of expel of a swelling agent from a swelling agent saturated polymer foil induc ed by a second organic liquid (i.e., blowing agent for foaming of poly mers) has been set up and tested. The method was applied to acetone sw ollen polyetherimide (PEI) foil and 1,1,1-trichloroethane and ethanol (blowing agents) systems. By combining the results of radiotracer meas urements with those obtained by measuring foil weights, the amount of the respective blowing agents that replaced acetone in the PEI foil wa s determined.
