The theory and experimental work are described for the determination of the hydrogen peroxide permeability for various polymers at room and elevated temperatures. Compatibility tests indicate that many polymers decompose 90% hydrogen peroxide appreciably, while the effects of others are negligible. The appearance of some polymers remains unchanged after immersion in this reagent. The steady‐state diffusion rate through several polymers was measured in a permeameter constructed of Teflon. The hydrogen peroxide which permeated any film was determined quantitatively by means of a spectrophotometric method. Experimental curves of the amount permeated as a function of time agree with those predicted theoretically. A correlation was found between water vapor and hydrogen peroxide permeabilities for several polymers at room temperature. The hydrogen peroxide permeabilities of many polymers measured at 74°C. vary over four orders of magnitude. The temperature dependence of hydrogen peroxide permeabilities was found to conform to the Arrhenius type relationship. Activation energies for hydrogen peroxide permeation through plasticized polyvinyl chloride and polyvinylidine chloride were found to be 16 and 18 kcal./mole, respectively.
