ABSTRACT:
Disclosed are various fluoropolymer blend combinations and multilayer articles comprising a blend in a first layer and a second layer comprising a polymer bonded to the first layer. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, and a second layer bonded to the first layer, the second layer comprising a partially-fluorinated thermoplastic polymer, a perfluorinated thermoplastic polymer, or a combination thereof. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, at least one of which comprises a partially-fluorinated thermoplastic polymer, and optionally at least one perhalogenated polymer, and a second layer bonded to the first layer, the second layer comprising an at least partially-fluorinated thermoplastic polymer. The invention also provides processes for preparing blended fluoropolymers and multilayer articles comprising a fluoropolymer layer.
