Application of 4 4'-Oxydianiline
1. It is one of the important raw materials for high temperature resistant resins such as polyimide, polyetherimide, polyesterimide, polymaleimide, and polyaramid;

2. It is also the raw material for the synthesis of 3,3',4,4'-tetraaminodiphenyl ether, which is the main monomer for preparing a series of aromatic heterocyclic heat-resistant polymer materials.

3. It is also used as a raw material and cross-linking agent for high-performance heat-resistant epoxy resin, polyurethane and other synthetic polymers.

4. At the same time, it is also used in the production of azo dyes, reactive dyes and perfumes to replace benzidine which has carcinogenic effects.
