The invention relates to a dendritic polymer and particularly relates to a dendritic polymer with a high refractive index and a preparation method thereof. The dendritic polymer with the high refractive index is prepared by reaction on a dendritic polymer and a benzene ring or sulfydryl-containing organic compound under the action of a catalyst and a high-temperature-resistant oxidant, wherein the dendritic polymer is one or more of PAMAM-G1, PAMAM-G2 or PAMAM-G3; the benzene ring-containing organic compound is one or two of benzoic acid or hydroxyl salicylic acid and the sulfydryl-containing compound is one or more of thiosalicylic acid, sulfydryl sulfonic acid or sulfydryl phenylboronic acid. The dendritic polymer with the high refractive index as an additive is added into well-illuminated epoxy resin and an organic silicon material, so that the refractivity can be remarkably improved. The preparation method provided by the invention is simple in process and easy to realize.
