Abstract: Methods and systems for analysis of the polymerization material of high pressure polymerization processes are provided. In certain embodiments, the methods and systems subject the polymerization material to Raman spectroscopy analysis. The Raman spectroscopy provides analysis of reaction mixtures and/or product streams in high pressure polymerization processes. The Raman spectroscopy analysis may include both compositional and characterization analysis of the reaction mixtures and product streams. The spectroscopy results can be used to provide process control feedback to adjust operating parameters of the reactor operations and/or an associated polymerization product handling and finishing processes.

Abstract: Methods are provided for determining and controlling polymer properties on-line in a polymerization reactor system, such as a fluidized bed reactor. The methods include obtaining a regression model for determining a polymer property, the regression model including principal component loadings and principal component scores, acquiring a Raman spectrum of a polyolefin sample comprising polyolefin, calculating a new principal component score from at least a portion of the Raman spectrum and the principal component loadings, and calculating the polymer property by applying the new principal component score to the regression model. The property can be controlled by adjusting at least one polymerization parameter based on the calculated polymer property.

Abstract: Method and systems for online analysis of a polymeric material within a mixing device are provided. In certain embodiments, the methods and systems subject the polymeric material to Raman spectroscopy analysis. The Raman spectroscopy provides analysis of polymer properties that may include melt index, density, viscosity, molecular weight, molecular weight distribution, weight ratios of different polymers comprising the polymeric material, additive concentrations, crosslinking agent concentrations, scissoring agent concentrations, and combinations thereof. The spectroscopy results can be used to provide process control to adjust operating parameters of the mixing device and/or an associated polymerization process. The mixing device may be an extruder. The methods and systems may also include a processor for evaluating the results of the Raman analysis and automatically adjusting the mixing device and/or polymerization processes.
