Methods for determinau00c7u00e7o in real time the degree of tackiness of resins using a model for depressu00e7o temperature of iniciau00c7u00e7o of fusu00e7o.The present invention relates, in some ways, a method that includes the steps of: during a polymerization reaction, to produce a polymer resin in a fluid bed reactor, measuring the parameters of reaction that includes at least a temperature of the reactor, at least one proper of masses Dade resin,And the amount of at least one gas diluent condensu00e1vel in reactor; determining from at least a property measure of resin using a predetermined correlation, a value of temperature of initiation of fusion for a version of dry dry polymer resin; and during the reaction. Using a model of depression of temperature of initiation of merger to determine, in real time.A temperature reduced initiation of fusion for the resin (for example, a temperature at which it is expected that the resin starts to melt) in the presence of at least one gas diluent condensu00e1vel in reactor.
