Abstract:
A process for preparing a fluoropolymer/substrate composition, comprising:in the case of gaseous fluoromonomer(a) contacting a porous substrate with a solution comprising an initiator dissolved in a suitable solvent;(b) exposing said substrate and said initiator to gaseous fluoromonomer under polymerization temperature and pressure conditions wherein the fluoromonomer polymerizes into said substrate;or in the case of liquid, fluoromonomer(a) preparing a solution comprising initiator and liquid fluoromonomer;(b) contacting a porous substrate with said solution; and(c) polymerizing the liquid fluoromonomer under polymerization temperature and pressure conditions wherein the fluoromonomer polymerizes into said substrate, optionally in the presence of gaseous fluoromonomer.
