Abstract:
Mechanical properties of heat curing acrylic resin obtained by polymerization for long period of heating at a temperature lower than conventional temperatures were examined. The mechanical properties of the resin were lower than those of the resin cured at 100 degrees C. The results of high performance liquid chromatography and differential scanning calorimetry suggested that the poor mechanical properties were due to significant amounts of residue monomer and benzoyl peroxide in the resin, but is not to changes molecular weight.
