Process for the preparation of low fuming fluoropolymer

摘要

The present invention relates to the reduction of oligomer content of melt-processible fluoropolymer so that the fluoropolymer has at least 25 ppm less oligomer than the as-polymerized fluoropolymer, the reduction being obtained by melting the fluoropolymer forming a surface of molten fluoropolymer and regenerating this surface, contacting the regenerating surface with inert gas, and devolatilizing the resultant molten fluoropolymer.
