WebThe resins for examination by FTIR were prepared as already reported.' All the FTIR spectra were initially col- lected on a JASCO 5000 FTIR, but as a zooming facility was needed to observe some of the small variations in the percentage transmission of the bands involved, a Mattson Galaxy 4020 FTIR with a zooming facility was used. All Webthe bisphenol A polycarbonate are 16,000 and 28,000, respectively. 2.2. TGA/FTIR analysis and sampling of evolved products . TGA/FTIR was carried out at a heating rate …
