Abstract
The invention provides a process, and product thereof, for forming a chemically resistant fusion bonded between chemically dissimilar materials by use of an acid-based terpolymer for protective garments. The olefin terpolymers are preferably copolymers of an olefin, an acid and an ester. The process involves placing the olefin terpolymer film between two dissimilar films such as a facepiece and the fabric material of the garments and applying heat and pressure. The resulting fusion bonded film composite is strong, flexible and upon the application of sufficient stress exhibits total cohesive rupture failure.
