Abstract: A new acetylene terminated nitrophenyl sulphone (ATNPS) has been synthesized by nucleophilic displacement reaction between bis(4-chloro-3-nitrophenyl)sulphone and 3-ethynyl aniline. ATNPS is characterized by elemental analysis, IR and 1H-NMR spectroscopies. On heating at ca. 250ᵒC or above ATNPS becomes cross linked due to the presence of the acetylenic end group. The thermal behavior has been studied by DSC and DTA techniques. The kinetic study of the curing has been carried out by both differential and integral methods by use of a computational programming.
