Abstract
The present invention relates to a fluorine-containing polymer comprising a structure represented by the following general formula (I), as well as the preparation process and use thereof. According to the technical solution of the invention, a novel fluorine-containing polymer with a larger molecular weight and an aromatic side group is obtained through a simple reaction, and it can be used as a non-ionic fluorine carbon surfactant, and especially, is applicable to the preparation of a pigment dispersion. Additionally, the invention further relates to a pigment dispersion and the preparation process thereof. In the invention, a little non-ionic fluorine carbon surfactant is added into a traditional pigment dispersion, whereby the interface energy in the pigment dispersion system can be improved, and the aggregation and agglomeration of pigment particles are prevented, as a result, the particle diameter and viscosity are less changed with the lapse of time, and there is no precipitate occurred, therefore, the stability of the pigment dispersion is improved significantly.
