Diffusion, permeation, and solubility of selected agents in and through polyethylene

Surface differences and solute permeability in films of certain acrylic–methacrylic ester polymers

“…A permeability cell ( Fig. 1) was constructed in perspex after Gonzales et al 9 It consists of two chambers separated by the film under investigation. The assembled cell was ascertained leak proof15 and the experiment was conducted in a thermostatically controlled waterbath a t 36.98' (standard deviation, 0.005").…”

Steady-State and Nonsteady-State Transport through Membranes Using Rotating-Disk Electrode Polarography: Description and Properties of a Rapid Response New Technique

“…In most instances (1- 6,9), the actual measurement of membrane permeation has been conducted along rather classical lines where the barrier separates two compartments of solution, the contents of which are sampled as a function of time.

Effects of Structure on Permeability of Substituted Anilines from Aqueous Solutions through Polyethylene

“…Polack et al (2) formulated a method for predicting the permeation of selected solutes in aqueous systems when the products (in polyethylene containers) were autoclaved. Gonzales et al (3) studied the permeation of aqueous solutions of selected compounds through polyethylene and reported that structure influences the permeability constant. Other investigators (4-7) studied the permeation of solute molecules through different types of polymeric materials.…”
