Abstract
Process for the emergency stopping of a polymerization reaction in the gas phase, comprising the injection of a poison of the reaction into a polymerization reactor and the evacuation of the gaseous content of the polymerization reactor via delaying means to a burner at the maximum limited feed rate, characterized in that the delaying means simultaneously serve to obtain a homogeneous distribution of the poison of the reaction inside the polymerization reactor so as to interrupt the polymerization reaction, and to regulate the flow of gasses evacuated to the burner so as not to exceed the maximum feed rate of the burner.
