Abstract
The phenylethynyl end-capped imide model compounds 6F-PDA-PEAP and 6F-ODA-PEAP were prepared for detailed investigation of the thermal cure process. To probe the spectral changes of ethynyl C C moieties as well as imide rings and phenyl rings in PDA and ODA units during the thermal curing, we applied two-dimensional (2D) correlation analysis to the infrared spectra of 6F-PDA-PEAP and 6F-ODA-PEAP films. Thermal curing of 6F-PDA-PEAP and 6F-ODA-PEAP was influenced by molecular structure, and it induced spectral changes of C C moieties as well as imide rings and phenyl rings in PDA and ODA units. The thermal curing of 6F-PDA-PEAP and 6F-ODA-PEAP films induces the intensity changes of bands of imide and phenyl rings in PDA and ODA units before that of C C moieties. (C) 2011 Elsevier B.V.
