Abstract
Activation of thermoplastics, such as polyphenylene sulfide, polysulfone, and polyether sulfone thermoplastics by subjection thereof to bromine is disclosed. The activation process is carried out at relatively low temperatures, such as below 200.degree. F. and illustratively, may be carried out at room temperatures. The bromine, in the illustrated embodiment, is provided in an aqueous solution with or without acids or halide salts. The halide salts, when utilized, provide control of the activity of the bromine. The process advantageously adapted for activating the thermoplastic material where it is intended that it serve as a substrate for use in accepting copper plating, as in printed circuit board manufacture.
