The latest developments of foreign antioxidants

In the process of manufacturing, processing and use, polymer materials will inevitably come into contact with oxygen in the air and be oxidized, resulting in damage to the appearance and decline of physical properties, which seriously affects its commercial value. In order to prevent the oxidation of the polymer, people try to eliminate the unstable groups in the molecule by changing the chemical structure of the polymer, and synthesize a polymer with inherent antioxidant properties. This effort has achieved certain results, but due to the price, Due to performance and processing reasons, very few varieties have been used in practical applications. Studies have found that for most polymers, adding antioxidants is a simple and effective way to improve their antioxidant properties.
