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.

Abstract: HOE 75/F 905 PROCESS FOR THE MANUFACTURE OF HOMO- AND COPOLYMERS OF TETRAFLUORETHYLENE Polymers on the basis of tatrafluoroethylene are produced in the presence of a redox system as catalyst consisting of a usual peroxidic compound as oxidizing component and a water-soluble nitrogen compound liberating in situ a diimine under the polymerization conditions. The polymers obtained can be processed, inter alia, into thick walled articles on a ram extruder or into large sintered block free from crack formation.
