Abstract: THE PRESENT INVENTION RELATES TO AQUEOUS DISPERSIONS OF POLYMERS ON THE BASIS OF POLYTETRAFLUOROETHYLENE. THE POLYMERIC PARTICLES HAVE AN AVERAGE DIAMETER OF 0.2 TO 0.5U AND CONSIST OF A CORE MADE FROM 90-99% BY WEIGHT OF TETRAFLUROETHYLENE AND 1-10% BY WEIGHT OF CERTAIN HALOGEN CONTAINING COMONOMERS AND A SHELL OF TETRAFLUOROETHYLENE HOMOPOLYMER. THIS POLYMERIC MATERIAL HAS IMPROVED PROPERTIES FOR PASTE EXTRUSION PROCESSES.
