CONTROL OF THE PROCESS OF STYRENE POLYMERIZATION IN NONSTATIONARY CONDITIONS

The mathematical model of the process of suspension polymerization of styrene has been developed under nonstationary conditions caused by a poisoning effect on the initiator of phenylacetylene entering to polymerization with styrene and leading to a decrease in productivity by polystyrene. To avoid this problem the nonstationarity function has been suggested using of which it together with the equation of the monomer consumption rate will permit correcting the change of initiator activity with time and keeping the productivity at the required level
