Abstract:
A method for predicting one or more polymer latex properties for an emulsion polymer latex, comprising the steps of:conducting an emulsion polymerization process in a reactor including one or more reactor inputs to produce an emulsion polymer latex; measuring a set of process parameters for the emulsion polymerization process; performing a heat balance and a mass balance across the reactor based on the set of process parameters measured in said measuring step to determine a set of calculated polymer latex properties for said emulsion polymerization process; and determining one or more predicted polymer latex properties for the emulsion polymer latex being prepared in the emulsion polymerization process using the set of process parameters, the set of calculated polymer latex properties, and a predetermined set of statistical relationships between the process parameters, the calculated polymer latex properties and the polymer latex properties to be predicted.
