AI Technical Summary

Technical Problem

Resin compositions containing polyolefin resins deteriorate due to heat and oxygen, leading to decreased strength, changes in flowability, and surface properties, with existing antioxidant combinations losing effectiveness over time.

Method used

A composition comprising a specific phenolic compound and a phosphorus-based compound with a molecular weight of 550 or more, in a specific ratio, is used to stabilize organic materials, enhancing antioxidant performance even after long-term storage.

Benefits of technology

The composition provides excellent antioxidant performance, preventing deterioration and maintaining material properties over time, particularly in the presence of oxygen.
