Abstract | The influence of styrene content and thickness of the samples on the UV curing of Vinyl ester/Styrene resins (VERs) was investigated by DSC and the combination of TGA and FT-IR (TGA-FTIR). The glass transition temperatures of the network polymers after curing were found to be lower for the VERs with higher styrene content. The released heat during UV curing further increased the Tg, with this increase being proportional to the volume of the resins. Within the range of thickness investigated (up to 30 mm) the relative amount of emissions of ST, VE and CO2 were found to be the similar at the top and at the bottom of the samples. Similar results were obtained from the TGA analysis, indicating that the VERs were fully or almost fully cured all along the cross section. A good correlation was found between the analysis of the thermal properties by DSC and the results obtained by the TGA-FTIR system. |
