Synthesis of poly (phenylene ether sulphone)s containing aminated chain units

Add time:07/26/2019    Source:sciencedirect.com

Amino groups have been introduced into the phenylene rings comprising poly (phenylene ether sulphone) (PES) chains by performing nitration/reduction procedures on preformed PES and by using an aminated dichloride as a comonomer to achieve direct synthesis of aminated PES by polycondensation. It appears that side reactions can occur which cause problems with nitration/reduction procedures. The use of 2-amino-4-chlorophenyl sulphone as comonomer provides an effective means of introducing amino groups, but the copolymers obtained had inherent viscosities lower than that of homopolymer made by a comparable polycondensation procedure.
