Abstract

Measuring product properties during vinylacetate‐ethylene (VAE) polymerizations can be difficult due to economic and technical limitations. The use of soft sensors, mathematical methods using available process data (current and historic), can be an effective solution to infer the sought after property and calculate properties not directly measurable. The setup of a soft sensor in an industrial environment for a long term, successful application needs to take into account several additional hurdles. These include the variability of the process, soft factors leading to the acceptance of this tool in production, and the effort needed for long‐term support and maintenance among others. These points are illuminated using the successful development and implementation of a VAE dispersion process based tile adhesive tensile strength soft sensor. image
