AI Technical Summary
Existing hindered phenolic antioxidants are ineffective when used alone, and their combined use affects material properties. They also lack the ability to improve the thermal properties, micro-aggregation properties, and rheological properties of materials.
A novel phenolic antioxidant with hindered monoalicyclic diamide was synthesized via a nucleophilic addition-elimination reaction. A specific monoalicyclic diamine and 3-(3,5-alkyl-4-hydroxyphenyl)propionate were used to form an antioxidant with amide bonds, thereby optimizing the material properties.
It improves the antioxidant properties of materials, enhances thermal stability, micro-aggregation and rheological properties, has a simple preparation method with high conversion rate, and the solvent can be recycled, making it highly competitive in the market.
