Abstract
This paper describes the permeation process as related to protective clothing materials and some new applications of physical-chemical tools which may help to furnish the industrial hygienist with some predictive techniques. Values for the three-dimensional solubility parameter (3-DSP) for ten polymers are reported, and new developments regarding this parameter and its relation to glove selection are discussed. Limitation of the use of 3-DSP and future attempts to resolve the problem of proper protective clothing selection are also discussed.
