| abstract |
The present invention relates to a method of making a fluoropolymer object comprising: - providing a substrate made of a fluoropolymer comprising units derived from the monomers M 1 , M 2 and M 3 , wherein: °M 1 is vinylidene fluoride; °M 2 is a monomer of formula (I): CX 1 X 2 =CX 3 X 4 , wherein X 1 , X 2 , X 3 and X 4 are independently selected From H, Cl and F, and wherein at least one of X 1 , X 2 , X 3 and X 4 is F; °M 3 is a monomer of formula (II): CY 1 Y 2 =CY 3 CF 3 , wherein Y 1 , Y 2 and Y 3 are each independently selected from H, Cl, F, Br, I and optionally partially or fully halogenated alkyl groups containing 1 to 3 carbon atoms; stretch. |
