1.1 This test method describes the collection of absorption spectra of polyetheretherketone (PEEK) polymer in filled and unfilled grades, as supplied by a vendor, and the subsequent calculation of the percent crystallinity. The material is evaluated by infrared spectroscopy. The intensity (height) of the absorbance peaks is related to the amount of crystalline regions present in the material.
