Method for online determination of the degree of resin stickiness using the model for the drop in the melting initiation temperature

摘要

In some embodiments, the polymerization reaction to produce a polymer resin in the fluidized bed reactor, the reactor temperature, the characteristics of one method, condensable diluent in at least one reactor at least a resin least Using a step of measuring the reaction parameters, including the amount of gas, a correlation which is set in advance, the measured resin properties of one, determining a dry melt initiation temperature values ​​for the dry version of the polymer resin, at least, During the reaction, in an online fashion using a melt initiation temperature depression model, the temperature which is considered reduced melt initiation temperature of the resin (for example, a start to melt the resin in the presence of condensable diluent gas of at least one reactor I and a step of determining a).
