Abstract
The formation of conjugated double bonds in polyvinylchloride (PVC) films b y ultraviolet (UV) irradiation is analyzed using an in situ laser-monitorin g technique we have developed to measure changes in transmittance of thin U V-irradiated PVC films. Conjugated polyenes of different lengths are produc ed by laser irradiation at 193 and 248-nm wavelengths. This technique promi ses to have broader applications in the study of polymer reaction mechanism s and kinetics. (C) 2000 John Wiley & Sons, Inc.
