4,4'-Oxydianiline（ODA) CAS 101-80-4

Usage:

1）It used as a monomer of high temperature resistant polymeric material polyimide, also used in the plastics industry；

2）It is one of the important raw materials of new special engineering plastic polyimide, polyetherimide, polyester imide, polymaleimide, polyarylamide and other high temperature resistant resins;

3）It is also the raw material for the synthesis of 3,3', 4,4' -tetraminodiphenyl ether, which is the main monomer for the preparation of a series of aromatic heterocyclic heat resistant polymers；

4）It is also used as a raw material and crosslinking agent for high performance heat resistant epoxy resin, polyurethane and other synthetic polymers. 4. At the same time, it is also used to replace benzidine with carcinogenic effect in the production of azo dyes, reactive dyes and spices. At present, diaminodiphenyl ether has been used as Chemicalbook raw material to develop direct dyes of different color levels, such as bright red, brilliant red, sand red, yellow brown, green, gray, blue, brilliant orange, black, etc., which can be used for dyeing silk, wool, cotton, linen and other fabrics, and its color fastness and dyeing rate are superior to benzidine dyes.
