Synthesis ofBismaleimidei.e.bis (4-maleimidophenyl) Sulphone (B) and Michael adduct of B with 4,42 - Di amino Diphenyl methane and blended with allylnadicimides i.e. bis (4-allylnadicimidophenyl) methane (S) ,1,6-allylnadicimidohexane(V) , and N-allylnadic-imide(L) was carried out at 280 ºC for 1hr. The cure behavior of the blend resins was measured by DSC.The thermal stability of cured resins was characterized by thermogravimetricanalysis.The thermal stability of the resins improved markedly with the higher content of chain extended bismaleimide (M) with solid allylnadic-imide resin in blends.
