Zusammenfassung:	The invention relates to a preparation method and an application of a multifunctional hybrid synergistic antioxidative stabilizer formed through an ether bond, thioether bond, amine and amido bond stable connection mode. The preparation method comprises the following steps: adding alcohol or sulfur or the amine to an anhydrous THF, DMF, acetone, ethyl acetate or acetonitrile solvent of NaH or NaOH under the protection of nitrogen, stirring, dropwise adding iodide, bromide or chloride to prepare NaI or KI or activated alcohol, and stirring or heating; adding a saturated NH4Cl water solution and an organic solvent, extracting, drying an organic phase through Na2SO4, filtering to remove an organic solvent to obtain a solid product, and purifying an oily or liquid product. The multifunctional hybrid synergistic antioxidative stabilizer has the characteristics of stably-bonded multifunctional hybrid synergistic property, heat resistant property, light resistant characteristic, high-temperature processing resistance, hydrolysis resistance, acid resistance, alkali resistance and the like, thereby making up the weakness of a similar product on the existing market and laying the foundation for developing a new generation effective antioxidative stabilizer.
