Abstract
A novel diamine with built-in ether and amide structure was prepared via two-step reactions. Nucleophilic reaction of 4,4′-oxydianiline with 6-chloronicotinoyl chloride led to preparation of N,N′-(oxybis(1,4-phenylene))bis(6-chloronicotinamide) (OPCN). OPCN was reacted with 4-aminophenol to provide a novel diamine (EADA). After complete characterization, the prepared diamine (EADA) was used to prepare related polyureas by reaction with different diisocyanates. The obtained poly(ether-amide- urea)s were characterized and their properties were studied. Improved thermal stability was observed for the prepared polyureas in comparison to the common ones. This modification extends application of these polyureas in various industrial purposes.
