POWDERS OF FLUORINE-CONTAINING POLYMERS HAVING A HYDROPHILIC SURFACE AND A METHOD FOR THEIR PREPARATION

摘要

The present invention provides fluoropolymer powders having a diameter of from about 0.05 to about 200 microns, said powders having pendant hydrophilic groups and olefinic unsaturation. The powders are useful in applications which require a hydrophilic form of a fluropolymer powder such as poly(tetrafluoroethylene), such as a binder component in inks and coatings, or as components for paste extrusion or as components of composite materials.
