摘要：

Fluorescence emission and excitation spectra of dilute tetrahydrofuran solutions of thermally degraded PVC, (TPVC), photochemically degraded PVC, (PPVC), chemically degraded PVC, (CPVC) and non-degraded PVC are compared. The spectra of CPVC and PPVC are similar and are composed of a mixture of polyene structures while those of TPVC are different. The reasons for these differences are discussed. © 1979.
