COPOLYMERS CONTAINING VINYLIDENE FLUORIDE AND TRIFLUOROETHYLENE |
| 摘要 |
The subject matter of the invention is a copolymer obtained by free-radical copolymerization of vinylidene fluoride with trifluoroethylene and of at least a third monomer, the third monomer having a molar mass greater than 0 g/mol and corresponding to the formula: in which R1 is a hydrogen atom or a fluorine atom, and R2 and R3 are chosen, independently of one another, from Cl, F and CF3, and the functional groups are selected from phosphonate, carboxylic acid, SO2X (where X is F, OK, ONa or OH) or Si(OR)3 (R being a methyl, ethyl or isopropyl group) groups. The invention also relates to a process for preparing this copolymer. |

1. A random linear copolymer obtained by copolymerization of vinylidene fluoride, of trifluoroethylene and of at least one third monomer, the third monomer having a molar mass of greater than 100 g/mol and corresponding to the formula:in which R1 represents a hydrogen atom or a fluorine atom and R2 and R3 are chosen, independently of one another, from Cl, F, CF3, phosphonate, carboxylic acid, SO2X, where X represents F, OK, ONa or OH, or Si(OR)3, R representing a methyl, ethyl or isopropyl group. |
