ABSTRACT:
Improved polymer barrier for protective garments for personal protection against hazardous chemicals (e.g. epoxy products, organic solvents and pesticides) and a rational method of selecting polymer membranes with optimal permeation resistance against hazardous chemicals. As an excellent barrier against epoxy products and solvents a protective garment contains a membrane of a vinyl alcoholethylene copolymer. Said copolymer was selected by the invented optimization method (the three dimensional solubility parameter concept).
