Epoxy resins. III. Application of fourier transform IR to degradation studies of epoxy systems

Abstract: Three cured epoxy resins were investigated under various degradation conditions by Fourier transform infrared (FTIR) spectroscopy for measurement. The epoxy resins were the diglyadyl ethers of bisphenol A (DGEBA), phenolphthalein (DGEPP), and 9,9‐bis(4‐hydroxyphenyl)fluorene (DGEBF). The thermal stability order of functional groups that incurred DGEBA was total methyl group ∼ total benzene ring > methylene > p‐phenylene > ether linkage > isopropylidene. The oxidative thermal and photodegradation pr… Show more

“…The employed apparatus was a Nicolet 510 equipped with a Spectratech IR-plan microscope. The IR bands (Table I) were attributed using reference works, 10 -12 the results of Lin et al, 4 and especially those of Stevens, 13,14 and by comparing the spectra of the constituents with those of the 2 crosslinked systems (Fig. 1).…”

“…They may also be those of carboxylic acids resulting from Norrish-type reactions from ketones. 6 In both cases we link the formation of this CAO band at 1720 cm Ϫ1 to the presence of a positive band at 1165 or 1168 cm…”
