Abstract
In a polymerization process utilizing a high pressure flash to separate polymer from unreacted monomer contained in the effluent stream from the reactor, the concentration of unreacted monomer in the reaction effluent is determined by withdrawing from the reactor an effective analyzing amount of effluent, exposing the amount to a low pressure flash and analyzing the vaporized portion to determine the concentration of monomer.
