Abstract
The invention relates to a polymer comprising structural units of vinylidene fluoride, trifluoroethylene and chlorotrifluoroethylene, the molar ratio between the vinylidene fluoride and the trifluoroethylene in the polymer being between 55:45 and 65:35, and the molar proportion of the structural units of chlorotrifluoroethylene in the polymer being between 1.5 and 4.5%. The invention also relates to various items comprising said polymer, such as films, fibres, extruded plates and moulded items.
Claims22
