摘要： The techniques disclosed provide a treatment method for passivating the interior surface of a polymerization reactor to minimize the formation of a polymer coating on the surface. The passivation is performed using a passivating agent that reacts with adsorbed water to form labile passivation products. Both the passivating agent and passivation products may be easily removed from the reactor prior to polymerization. Other embodiments provide a reactor system with a tank configured to automatically add a passivating agent to the reactor and processes for making polymers using a treated reactor.
