摘要: A fluoropolymer block copolymer containing a hydrofluorocarbon and a polyamide-based crosslinking agent crosslinked at a temperature above about 500° F. (about 260° C.). The crosslinked-block copolymer has compatibility with both non-hydrofluorocarbon-based fluoropolymers and engineered resins. Additionally, the block copolymer has unexpectedly high temperature stability, higher than each of the individual components.
