Definitions
- the present disclosure relates to fluorine-containing copolymers.
- US Pat. No. 5,300,003 discloses a multilayer polymer structure comprising at least two adjacent layers of fluoropolymer, one of said layers comprising a perfluoroalkoxy polymer and the adjacent layer comprising a fluorinated ethylene-propylene polymer.
- a multi-layer polymer structure is described comprising:
