In order to realize the intellectualization of vinyl chloride suspension polymerization process,an on-line measurement flow diagram,measurement and calculation models were set up based on the principle of computer collecting and distributing control.The software including the data collection and treatment,model calculation and display interface was developed,and the on-line measurement system for polymerization conversion,polymerization rate and heat transfer coefficent was established.This system was tested on the practical vinyl chloride suspension polymerization process for nearly 200 batches,and the results showed that the maximum error was less than 2%.The development and application of this system have very important influences on the optimization of initiator system and operation conditions,the shortening of polymerization time and the improvement of production capacity.
