AbstractAcrylate resin derived from tetramethylol DDT resin have been synthesized and characterized by IR, NMR and CHN. Several IPNs were prepared from the unsaturated resins and commercial unsaturated polyester (palatal).Also the amine resins was used as hardener for epoxy resins and resole.The new IPNs were curable at room temperature according their curing characteristics were investigated by DSC technique, several parameters were found; i.e. curing temp., rate of curing, curing energy and activation energy.The thermal stability and thermo-oxidative stability of new resins and their IPNs were studied by TGA technique in the presence of inert atmosphere. Several thermal stability parameters were calculated from TG thermograms. The obtained results confirmed the outstanding thermal stability of new IPN’s.
