摘要：

A suitable rheometer for simultaneous dynamic mechanical analysis (DMA) and NIR (Near Infra-Red) in situ 1 analysis during UV curing was developed. The conversion and viscoelastic properties of a dimethacrylate/styrene-based system were investigated. The results were plotted against both it-radiation time and total, average conversion. For the same conversion, a lower intensity delays the reaction but does not affect the viscoelastic properties.
