“…The photoresist SU-8 exhibits no melting point within the considered temperature range of up to 320 C. The area below the melting peaks is defined as the heat of fusion DH f of the material under test. For PFA and FEP, the heat of fusion can be determined to 20.7 J/g and 11.9 J/g, respectively, which is in good agreement with values found in literature [26].…”

“…Poly[tetrafluoroethylene‐ co ‐(perfluoropropyl vinyl ether)] (PFA)11 has a unique role in the plastics industry due to its inertness, heat resistance and low coefficient of friction in a wide temperature range. Generally, fluorinated compounds and fluoropolymers have excellent chemical resistance, oil resistance and oil‐ and water‐shedding resistance 12–15.…”

Spherulitic textures of poly[tetrafluoroethylene‐co‐(perfluoropropyl vinyl ether)] (PFA) were examined in detail using polarized optical microscopy. The PFA consisting of random comonomer units among the tetrafluoroethylene units crystallizes as spherulites composed of lamellae, although polytetrafluoroethylene usually forms extended‐chain crystals because of the rigid nature of 13/6 helices. The spherulites obtained exhibit positive birefringence since the polymer crystal has a larger refractive index in the direction normal to the chain than that along it. These fluorocopolymers exhibit a thicker long period of at least 30 nm in small‐angle X‐ray scattering profiles than is generally the case for hydrogenated crystalline polymers. In these copolymers, we consider the formation of a switchboard‐type lamellae model according to P. J. Flory's suggestion. In addition, we find the overlooked reflections near 2θ = 8.5° based on the superlattice in wide‐angle X‐ray diffraction profiles of fluorocopolymers with high reproducibility. From this result, it was found that the lattice constant that was previously proposed is required to be refined to twice the value on the a‐ and b‐axes of the reciprocal lattice to assign all the reflection indices.
