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.
