Fluoropolymers with Very Low Amounts of a Fluorinated Alkanoic Acid or its Salts |
| abstract |
Method of reducing the amount of a fluorinated acid or its salts from a fluoropolymer, the method comprises: (i) providing a composition containing particles of the fluoropolymer, (ii) contacting the fluoropolymer particles with a treatment composition comprising at least one organic liquid; and, optionally, further comprising (iii) isolating, washing and subjecting the fluoropolymer to drying treatment, and wherein the fluoropolymer contains units derived from tetrafluoroethene (TFE) and is selected from the group of fluoroelastomers and the group of fluoropolymers having a melting point of less than 150° C. Also provided are fluoropolymer and compositions containing such polymers that are essentially free of fluorinated acids and their salts. |
