Abstract: The present invention relates to a polymeric composition comprising a first polymer component C being selected from TFE/PAVE polymers comprising a small amount of chlorinated monomers selected from chlorotrifluoroethylene and dichlorodifluoroethylene and a second optional polymer component D being selected from TFE/PAVE polymers and being free from chlorine. The polymeric composition of the invention is characterized in that it has a total Cl content of from 0.01 to 0.25% by weight. The composition of the invention has very good adhesion on metals and plastics despite a very low total level of chlorine.
