METHODS FOR DETERMINING TEMPERATURE VALUE INDICATIVE OF RESIN STICKINESS FROM DATA GENERATED BY POLYMERIZATION REACTION MONITORING

摘要

In some embodiments, a method including the steps of monitoring a polymer ization reaction which produces a polymer resin in a fl.mu.id bed reactor, w here a dry melt reference temperature is characteristic of melting behavior of a dry version of the resin, and in response to data indicative of at leas t one monitored parameter of the reaction, determining in on-line fashion a reduced melt reference temperature that is at least substantially equal to t he difference between the dry melt reference temperature and a temperature b y which the dry melt reference temperature is depressed by the presence of c ondensable diluent gas with the resin in the reactor. Optionally, the method also includes the step of controlling the reaction in response to the reduc ed melt reference temperature or a stickiness parameter determined from the reduced melt reference temperature.
