Permeability coefficients, E', for H2 in 10 different types of silicone polymer membranes were measured in the temperature range of 10.0-55.0Β°C and at pressures up to 100 psig ( -6.8 a t m ) . The values of P decrease slightly with increasing A p , the pressure difference across the membranes. The p

EPDM-silicone rubber blends prepared by melt mixing have been compression moulded into sheets and crosslinked by gamma irradiation. The permeability of the blends to methanol vapour has been measured at room temperature. It changes progressively with membrane composition and no threshold can be dete
The mechanism of the condensation reactions of CH 3 ions with CH4, NH 3 and H2S was studied. Apparently, neither a purely "direct" reaction nor complete equilibration of hydrogen atoms takes place. Evidence for intramolecular exchange of hydrogen atoms prior to H2 elimination was found.
