Abstract

In this paper time-of-flight secondary ion mass spectrometry is used to study the chemical modification, upon exposure to u.v. light of 185 and 254 nm in an Ar atmosphere, of the surfaces of polycarbonate derived from bisphenol-A (PC-A) and from the bisphenol of acetophenone (PC-B). On irradiation with u.v. light, the polycarbonates show main chain scissions and photo-oxidative reactions. By this treatment hydroxyl groups are introduced on the polycarbonate surface, which is confirmed by chemical derivatization reactions. In addition, evidence is presented for the occurrence of a Photo-Fries rearrangement.
