Characterization of poly(etheretherketone) and diallylphthalate-fiberglass composites by combined thermogravimetry mass spectrometry (TG/MS) and ancillary techniques. [Poly(etheretherketone), diallylphthalate]
Thermogravimetry/mass spectrometry (TG/MS) analyses and pyrolysis gas chromatography mass spectrometry (PY/GC/MS) have been utilized to determine the major and minor thermal decomposition products of poly(etheretherketone) (PEEK) and diallylphthalate (DAP) - fiberglass (FG) composite molding resins, which are used at Mound. PY/GC/MS has also been used to characterize the organic sizings applied to the glass fibers which are incorporated into DAP and PEEK plastics for added strength. TG/MS of commercial DAP-FG molding resins showed phthalic anhydride to be the major decomposition product of the o-DAP prepolymer; similarly, phenol was found to be the major degradation product for PEEK. PY/GC/MS results indicate the organic sizings applied to the glass fibers are phthalate or acetate based. TG kinetic data indicate superior lifetime estimates for PEEK versus DAP molded products when analyzed in air or an inert atmosphere. 6 refs., 15 figs., 1 tab.
