摘要：

Several polyvinyl chloride(PVC) compounds were prepared in a Haake Torque Rheometer, equipped with noninterchangeable rotors and an electrically-heated mixing head, at various processing times and processing temperatures, with a constant rotor speed of 60 rpm. A Seiko 220C Automatic Cooling Differential Scanning Caloriometer(DSC) was then used to characterize the degree of fusion of these compounds. Afterwards, a Cambridge 260 Scanning Electron Microscope(SEM) was used to study the morphological characteristics of these compounds. In this paper, a correlation has been established between the processing time and processing temperature and the degree of fusion of these PVC compounds.
