Embodiment 1
[0055] This embodiment is used to illustrate a method for preparing a composition, a capacitor polymer and a capacitor disclosed in the present invention, including the following steps:
[0056] With 0.07% by weight of tributyl phosphate, 0.01% by weight of 3,4-ethylenedioxythiophene-2-methyl carboxylate, and 99.92% by weight of 3,4-ethylenedioxythiophene, the above three substances Mix well to prepare a composition containing polymerized monomers, phosphoric acid ester compounds and end-capping agents.
[0057] The above composition is used as a polymerization raw material to prepare an aqueous polymer dispersion by free radical polymerization. The specific implementation process is: get 1753g water and 90.32g sodium polystyrene sulfonate, mix them uniformly at high speed in the disperser, under the protection of nitrogen atmosphere, control the temperature in the reactor to be 22°C, add 17.54g ferric sulfate aqueous solution (1.3 % concentration) and 7.25g of the above-ment...
