ABSTRACT:
A composition comprising a high-melting perfluoroplastic swollen at a swelling temperature to the extent of at least one percent with a solution of a second, lower-melting perfluoropolymer in a solvent; and an assembly made by contacting said swollen perfluoroplastic material with a surface of an interlayer at a first temperature, contacting another surface of the interlayer with a substrate and applying pressure to cause the interlayer to adhere to both the perfluoroplastic and the substrate and thus form an assembly, and heating the assembly to a second temperature.
