EXPANDABLE FUNCTIONAL TFE COPLYMER FINE POWER THE EXPANDABLE FUNCTIONAL PRODUCTS OBTAINED THEREFROM AND REACTION OF THE EXPANDED PRODUCTS

摘要

A functionalized TFE copolymer micropowder comprising a copolymer of TFE and at least one functional comonomer, the copolymer having a functional group pendent to the polymer chain, is disclosed. The functionalized TFE copolymer micropowder resin can be paste extruded and expanded. Methods of making functional TFE copolymers are also described. The expanded functional TFE copolymer material can be post-reacted after swelling.
