AbstractUltrasonic, temperature and pressure sensors were combined together to be used in a slit rheometer to investigate the relationship between ultrasound signals with the rheological properties of PP and PS in processing. It is found that ultrasonic signals can represent monotone changes of polymer relaxation for different polymers under different processing conditions, and it also can indicate the shear thinning of polymer melting. Under the certain processing condition, there is an exponential relationship between ultrasonic signals with the viscosity of polymers, while the former factor and index number increase with the temperature increasing. Maxwell equations were used to simulate the relaxation of polymers in slit die, and it is found that two parallel connections Maxwell can fit the relaxation process well. This work can be used to investigate the viscoelasticity of polymers during rheometer processing.
