Abstract
Chemical etching of thin foils of polymers which were irridiated with heavy ions in order to produce filters has already been done since lon g time. This paper reports on first attempts to produce microholes in rather thick filter material. Polypropylene (PP) was used as the mater ial to be etched because of its sufficient resistance against a large number of inorganic and organic chemicals. First experiments demonstra ted that micropores could be etched in up to 150 mum thick PP foils.
