Side substitution aromatic ester diphenol, preparation method and preparation method of mesomorphic epoxy monomer

Abstract

The invention relates to side substitution aromatic ester diphenol, a preparation method and a preparation method of a mesomorphic epoxy monomer. The side substitution aromatic ester diphenol has a general formula shown in the specification of the invention, wherein X stands for an aryl group with side substitution. In the preparation method of an aromatic ester mesomorphic epoxy monomer by using the side substitution aromatic ester diphenol, a synthetic period of the monomer is greatly shortened, the raw materials of the synthetic monomer are cheap and are easy to obtain, and the preparation method is simple and convenient.

Description

technical field The invention belongs to the field of liquid crystal epoxy resins, and in particular relates to a side chain substituted aryl ester diphenol and a preparation method thereof, and a method for preparing liquid crystal epoxy monomers by using side chain substituted aryl ester diphenols. Background technique Liquid crystal epoxy resin first appeared in the 1980s. It is an important thermosetting resin. It has excellent optical, electrical, thermal and mechanical properties. It is widely used in communications, electronic packaging materials, aerospace, military defense and other fields. . Liquid crystal polymer is a polymer that exists in a liquid crystal state under certain conditions. Compared with polymers, it has the molecular orientation and position orientation unique to liquid crystal phases. Compared with small molecule liquid crystal compounds, it has high molecular weight. and properties of polymer compounds. Due to its excellent mechanical properti...
