Solvent-free amide synthesis method and its use in synthesis of polymer antioxidant stabilizer

The invention discloses a solvent-free amide synthesis method and its use in synthesis of a polymer antioxidant stabilizer. Through eight reaction expressions, different structural amide-linked thioether high-temperature long-term antioxidant stabilizers, sterically hindered phenol thioether hybrid antioxidants and sterically hindered phenol amide-type antioxidants as desired products are synthesized. Compared with the most carboxylate-bonded antioxidants on the market, the different types of multi-functional hybrid structure antioxidants stably bonding to amide have the advantages of structure stability, acid resistance, base resistance, hydrolysis resistance, environmental degeneration resistance and good synergistic antioxidation activity and are novel antioxidant stabilizer products having performances satisfying novel material development requirements. The novel polymer antioxidant stabilizers solve the problem that the same type of the ester-linked antioxidant stabilizer on the market has an ester bond easily decomposed under acid and base conditions and can be easily hydrolyzed and the existing product DSTDP/DLTDP on the market produces a smell in use and processing and the degraded material releases VOCs. The novel polymer antioxidant stabilizers provide a strong support and more choices for development of novel polymers.
