Fluoroelastomer laminates having one layer of perfluoroelastomer with an ethylenically unsaturated hydrogen or perfluorophenyl and bromo- or iodo- cure site components and compounded with a K. sub. 2 AF curing system and a second layer of peroxide-curable polymer compounded with a peroxide curing agent. The laminates exhibit excellent high temperature adhesion and oxidative and fluid resistance.

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.

This invention relates to methods for preparing membranes of polyfluoroethylene (PTFE) and to the asymmetric membranes fabricated thereby. Such membranes are useful as separation and ultrafiltration membranes. The membranes are produced as a single layer. Method steps including contacting a substrate with a solution of PTFE in a perfluorinated cycloalkane solvent at a high temperature to cause a film of such solution to be coated on the substrate, removing the coated substrate from the solution and rapidly cooling it by contact with a second solvent, removing the coated substrate from the second solvent, drying the film, and optionally separating film from substrate.

A process for adhering high-melting perfluoroplastic materials is disclosed, which process comprises swelling a material comprised of a first perfluoropolymer with a solution of a second lower-melting perfluoropolymer, and then adhering the material to a substrate with an interlayer of the same second perfluoropolymer. The final assembly, as well as intermediate assemblies or compositions which can be made and stored, are also disclosed.
