Abstract

Copolymers of methyl methacrylate (MMA) and triethyleneglycol
dimethacrylate (TEGDMA) obtained by photoinitiated polymerization using Fe(III)
complexes were submitted to thermogravimetry (TGA) under dynamic air atmosphere
and N 2 , and differential scanning calorimetric analysis (DSC). Thermal events were
observed only between 90 - 110 °C. Glass transitions were observed at ca. 100 °C,
followed by an exothermic peak at 170 °C. The exothermic peak was assigned to a
thermal curing process due to the presence of unreacted vinyl groups of the monomers.
DSC revealed to be a useful tool to evaluate the curing completeness in this kind of
material, using small amounts of sample in relatively short time.
