✦ Synopsis

Abstraet--Copolymers were synthesized by polyaddition reactions of aromatic diamine (4,4'-sulphonyl dianiline) and aliphatic diamines (l,2-diaminoethane and 1,3-diaminopropane) with N,N'-arylenebismaleimides (N,N'-m-phenylene-N,N'-p-phenylene-, and N,N'-benzidine-), They were characterized by elemental analysis, i.r. spectra and viscosity. The thermal behaviour of copolymers was studied using Thermogravimetric Analysis (TGA). All the copolymers are stable up to 270. Polyamides are less stable than polyaspartimides.
