METODO PARA MONITOREAR REACCION DE POLIMERIZACION Y DETERMINAR T DE INICIACION DE FUSION QUE COMPRENDE MEDIR PARAMETRO DE REACCION (T Y/O PROPIEDAD DE RESINA Y/O CONCENTRACION DE GAS DILUYENTE EN REACTOR), DETERMINAR T DE INICIACION DE FUSION SECA Y |
摘要 |
In some embodiments, a method including the steps of: during a polymerization reaction producing a polymer resin in a fluid bed reactor, measuring reaction parameters including at least reactor temperature, at least one property of the resin, and amount of at least one condensable diluent gas in the reactor; determining from at least one measured resin property using a predetermined correlation, a dry melt initiation temperature value for a dry version of the polymer resin; and during the reaction, using a melt initiation temperature depression model to determine in on-line fashion a reduced melt initiation temperature for the resin (e.g., a temperature at which the resin is expected to begin to melt) in the presence of the at least one condensable diluent gas in the reactor. |
