Abstract
A modified fine powder polytetrafluoroethylene, and the process for preparing the polymer, in which the modifying copolymerizable monomer is a selected dioxole monomer. The composition is dispersion-process-produced and includes a core portion having a copolymer comprising repeat units provided by tetrafluoroethylene monomer and dioxole monomer, and a shell portion that is substantially free of dioxole units. The core and shell portions may contain perfluoro (n-propylvinyl) ether. The composition is useful for paste extrusion, such as in wire coating and tubing applications.
