Softsensor for morphology of polymers

A method of producing a soft sensor for a reference morphology of multiphase latex polymer particles synthesized in a production process, for use in monitoring and/or controlling the production process and/or optimizing production capacities of the production process, comprising:

• providing via an interface to a processing device;
• time series data from a reference polymerization process,
• a morphology functional, wherein the morphology functional describes the movement of polymer clusters in multiphase latex polymer particles since the instance of the polymer cluster-formation along a reaction progression, in a reaction process, by relating a movement of polymer clusters in multiphase latex polymer particles since the instance of polymer cluster formation to time series data of a reaction process
• determining at the processing device
• a reference trajectory of the morphology functional up to a reference observation point along the reference reaction progression based on
• the time series data from the reference polymerization process, and
• the morphology functional,
• providing the soft sensor, the soft sensor comprising
• a reference trajectory of the morphology functional determined from the reference polymerization process,
• the morphology functional and
• a sensor input for receiving time series data from a production process of the multiphase latex polymer particles
• an output for
• a) the reference trajectory of the morphology functional and a production trajectory of the morphology functional for the production process or
• b) a deviation between the reference trajectory and the production trajectory.
