A STUDY ON THE SEQUENCE DISTRIBUTION OF HEXAFLUOROPROPYLENE IN FEP COPOLYMERS
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.
