Abstract: The effects of pressure ranging from 0.1 to 6.21 MPa (0-900 psi@ on the curing of unsaturated polyester resins at 110°C were invtstigated by an approach of integrated reaction kinetics-rheology-morphology measurements using a pressure differential scanning calorimeter (DSC), an infrared spectrophotometer (IR), a Haake rheometer, and by using scanning electron microscopy (SEM). Increasing pressure was found to delay the gel effect, and a previously unknown plateau of kinetic-controlled region in the initial po…
