β¦ Synopsis
The resonantly enhanced Raman spectra of biphenyl glutarate diacetylene polymer chains in fully radiation pofymerfzed and partially thermally polymerized samples are reported. Details of the resonant enhancement in the region of the polymer electronic absorption were studied in partially polymerized sampIes. The rofe of defects in producing fluorescent emission and in broadening the optical absorption for radiation polymerized samples is briefly discussed.
