Combined mechanistic and genetic programming approach to modeling pilot NBR production: influence of feed compositions on rubber Mooney viscosity

Abstract

The process model comprised of a mechanistic model based on emulsion polymerization kinetics and a data-driven model derived from genetic programming is developed to correlate the feed compositions and process conditions to NBR Mooney viscosity.

Effects of mixing temperature on the extrusion rheological behaviors of rubber-based compounds

“…Specically, viscous ow is associated with the production rate, whereas the elastic property of rubber inuences the appearance and dimensional stability of the extrudates, 12 which further determines the quality and cost of the nal products. 13 Some familiar phenomena, for example, die swell and distortion of the extrudate, are considered to be caused by elastic memory. 12,14,15 In recent decades, the rheological behaviors of this viscoelastic rubber material have attracted increasing attention from academia.…”
