Synthesis and characterization of Eesterthiourea chloral acrylate resin and their Interpenetrating polymer networks (IPNs).


Esterthioureachloralacrylate resin was synthesized by condensation reaction between chloral and thiourea which then react with acrylic acid to form the mentioned resin. Several new IPNs based on new resin of epoxy were polymerized i.e.,. (1:1, 1:2, 1:3) portions of epoxy hardeners respectively, have been prepared . curing of the new IPNs was studied by DSC as a function of temperature, several curing parameters were determined i.e.,. rate of curing , curing energy and activation energy, according the optimum curing conditions were found. The obtained results showed that the curing energy of new resin decrease in presence of different portion of epoxy: hardeners and initial temperature of curing decrease as epoxy: hardeners portion increase
