THERMOANALYTICAL STUDY OF MONOMERS: BisGMA, BisEMA, TEGDMA, UDMA
Thermal behavior of BisGMA (bisphenylglycidyl dimethacrylate), TEGDMA (triethylene glycol dimethacrylate), BisEMA (ethoxylated bisphenol-A dimethacrylate), UDMA (Urethane dimethacrylate) monomers and one their mixtures was investigated by TG-DTA, DSC and coupled TG-FTIR. TG-DTA curves of monomers showed that the isolated compounds starts decomposition between 178-297oC and mixture of fotocured monomers starts decomposition at 250oC. The TG-FTIR was used to characterize volatiles released during the thermal cure before thermal decomposition. The DSC curves showed the glass transition, melting point and crystallization temperatures of the samples.
