Ultraviolet Stability of Polymers Containing the Hexafluoroisopropylidene Group

Abstract

The photodecomposition of four polymer series containing the hexafluoroisopropylidene (6F moiety was studied. We report herein the photostability of a poly(ether ketone) series when subjected to UV light in air. Replacement of isopropylidene with 6F results in decreased photostability for the PEKs as evidenced by changes in molecular weight and IR and UV-VIS spectra. Results for polyamides, Polyimides, and polyarylates are also under study.
