Webphoto-rheometer techniques. It is seen that the addition of the hyperbranched epoxy resin can increase UV conversion ( UV) and reduce gelation time (tgel). After photo-initiation polymerization (dark reaction) occurred, a second exothermic peak in the DSC thermogram takes place: namely, the WebNov 3, 2024 · A rheometer is an instrument which characterizes the flow of a substance in response to forces, its rheology. A viscometer measures a fluid’s resistance to deformation at a given rate. This gives a single parameter, viscosity, for the fluid. Newtonian fluids have a fixed viscosity at a given temperature. As the applied force is increased,…
WebNov 28, 2005 · Photopolymerization is a widely used technique to synthesize polymers and hydrogels. The commonly used ultraviolet (UV)-curable mono-, di- or multifunctional vinylated monomers are often volatile, causing difficulty in kinetics analysis such as photo-differential scanning calorimetry (PhotoDSC).
