Title:
POLYPHENOL ANTIOXIDANT AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/098670
Kind Code:
A1
Abstract:
Disclosed are a polyphenol antioxidant and a preparation method therefor and an application thereof. An antioxidant molecule designed in the present invention contains a hindered phenol functional group used as a main antioxidant, and further contains an alcohol amine skeleton unit having a metal ion bonding capability, so that a synergistic antioxidation effect can be achieved during polymer processing and use, and the antioxygen capability of unit mass of the antioxidant molecule is improved. By means of the antioxidant, the problem that a single-function antioxidant has a poor antioxidation effect on a high polymer material is solved, and the antioxygen capability of unit mass of the antioxidant molecule is improved. The preparation method has the advantages of low energy consumption, cheap raw materials, simple operation, easy recycling of materials, recyclable solvent, and high product yield and purity.
