Solid-state NMR experiments have been developed to probe crystallization behavior fluoropolymers (Progress Summary)
- Lawrence Livermore National Laboratory (LLNL), Livermore, CA (United States)
The FK-800 fluoropolymer elastomer is being developed as a replacement material for the Kel-F 800 binder in the plastic bonded explosive PBX-9502. These polymers are a random co-polymer of poly-vinylidene fluoride (PVDF) and poly-chlorotrifluoroetheylene (PCTFE) in nominal 1:3 ratio. Initial characterizations of the FK-800 replacement show similar characteristics as the legacy Kel-F 800. However, differences in bulk crystallinity and crystallization kinetics have been observed. These differences may be driven by small differences in the distribution of the monomers on the polymer backbone (sequence distribution).
