Process to prevent discoloring of an organic substance, composite stabilizer for organic materials and structure of polymeric

摘要

Organic substances, particularly polyolefins are stabilized with a combination of a hindered phenol antioxidant such as 2,6-di-t-butyl p-cresol (BHT) and sodium borohydride (SBH). The inclusion of SBH helps to prevent yellowing which otherwise tends to occur in substances stabilized with a hindered phenol alone.
