[0009] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0010] The technical scheme of concrete implementation of the present invention is:
[0011] A process for preparing thermally stable polyvinylidene fluoride, comprising the steps of:
[0012] 1) Put 0.6 parts by weight of hydrogen peroxide and 0.9 parts by weight of inorganic alkali solution into the reaction kettle, mix them evenly, then put in 15.2 parts by weight of hexafluoroethane solvent and 0.4 parts by weight of acryloyl chloride solution, and stir and react at -8.5°C for 36 minutes;
[0013] 2) Add 9.3 parts by weight of polyacrylic acid solution, 68 parts by weight of vinylidene fluoride monomer, and 3.8 parts by weight of chlorocyclopentane, stir and react at 34°C,...
