The degree of crystallinity and lattice parameters of FEP copolymers polymerized with different methods and with various hexafluoropropylene contents were determined by X-ray diffraction method. Studies were also made on their density
melting point
heat of fusion and composition.It is shown from our results that the monomeric sequences of hexafluoropropy-lene are more uniformly distributed in the molecular chains of the copolymers obtained by emulsion and dispersion polymerization than that obtained by suspension poly-merization.
