The invention discloses a liquid crystal polymer with ion groups and a preparation method for the liquid crystal polymer. The liquid crystal polymer with the ion groups is formed by virtue of polycondensation of one or more of diol, diphenol or diamine, monomers with ion groups and acyl chloride. The preparation method for the liquid crystal polymer with the ion groups comprises: adding one or more of diol, diphenol or diamine into DMF, THF, acetonitrile, ethyl acetate or DMSO to obtain a mixed solution I; adding an acid-binding agent into the mixed solution I to obtain a mixed solution II; slowly dropwise adding the acyl chloride which is dissolved into the DMF, the THF, the acetonitrile, the ethyl acetate or the DMSO into the mixed solution II to obtain a mixed solution III; and adding alcohol substances into the mixed solution III, and performing washing and drying to obtain the liquid crystal polymer with the ion groups. The liquid crystal polymer with the ion groups disclosed by the invention is applied to the fields such as car parts, precise electronic instruments, light-guide fibers, medical apparatuses and instruments, waterproof materials, textile field, heat insulation materials, energy storage materials, body armors or parachutes and the like.
