Problems solved by technology

Although organic polymers have the above advantages, commercially available organic polymers are easily oxidatively degraded under the action of heat energy, resulting in yellowing and degradation of mechanical properties
[0003] Therefore, in order to prevent the oxidative degradation of organic polymers, antioxidants are generally added in the extrusion process to reduce the degradation of organic polymers, so as to enhance the mechanical properties and heat resistance of organic polymers; however, antioxidants themselves may cause organic Polymer coloration and decreased processing stability
In addition, antacids are generally added during the extrusion process to inhibit the degradation of organic polymers caused by acidic substances; Decreased stability

Description

technical field [0001] The invention relates to a stabilizer composition and a modified polymer material, in particular to a compound stabilizer composition comprising hydrotalcite compounds and sulfur-containing carboxylates, and a compound stabilizer composition comprising the compound formula A modified polymeric material of a stabilizer composition. Background technique [0002] Existing organic polymers (such as polyolefins) have good chemical stability, mechanical strength, electrical insulation and product dimensional stability, and have the advantages of non-toxicity and easy processing, so they are often widely used as thermoplastic engineering plastics. Although organic polymers have the above advantages, commercially available organic polymers are easily oxidatively degraded under the action of heat energy, resulting in yellowing and degradation of mechanical properties. [0003] Therefore, in order to prevent the oxidative degradation of organic polymers, antiox...
