Abstract

PVC polymerization technology was developed to reduce polymerization time without deforming the PVC characters (especially color appearance), by which the total batch cycle time was remarkably reduced. Perester and diacyl derivative initiators were concluded to be effective, and the polymerization time was reduced from 4 h to 3 h by use of these initiators and reactor cooling technologies.<br>Simultaneously, the control of polymerization state and the conditions for emergency stop of polymerization by use of inhibitors were investigated for the sake of safety in short-time (high speed) polymerization, and a monitoring system was established for safer PVC polymerization.<br>Applying these technologies to present commercial plants is expected to result in greatly increased productivity and reduced cost.
