The laboratory preparation procedure of a recently developed unsaturated polyester resin was followed to prepare the resin on a large scale (10‐ and 200‐L pilot plant reactors). The process heating rate, reaction temperature, and agitator tip speed were kept constant on scale‐up. The resin was successfully reproduced and its properties were unchanged upon scale‐up. The effects of reaction temperature and inert gas flow rate on the polyesterification reaction rate were investigated. It was found that a 10°C increase in temperature or a 50% increase in the gas flow rate results in a 50% increase in the reaction rate.
