Antioxidants are a class of chemical substances, when only a small amount of their presence in the polymer system, can delay or inhibit the polymer oxidation process, so as to prevent the aging of the polymer and extend its service life, also known as "aging agents". The research direction of antioxidant has turned to the development of efficient multifunctional additives and reactive antioxidants. Ideal antioxidant should have the following conditions: ① should have high antioxidant capacity; ② good compatibility with resin, no precipitation; ③ Good processing performance. In the processing temperature of high polymer does not volatilize, does not decompose; ④ Good extraction resistance, insoluble in water and oil; ⑤ The color itself should be colorless or light. Non-polluting products; ⑥ Non-toxic or low toxicity; ⑦ Low price.
