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).
Claims17
A method for protecting skin against exposure to hazardous chemicals comprising positioning a protective garment adjacent to the skin, said protective garment comprising a substantially water insoluble polymer material, said polymer material being a copolymer of C.sub.2-5 alkene substituted with up to four hydroxy groups and a C.sub.2-5 alkene, or a homopolymer of a C.sub.3-5 alkene substituted with up to four hydroxy groups.
