    Abstract: A polymer can be prepared using a loop reactor and process including feeding a process stream through the loop reactor and maintaining the loop reactor at a steady state by controlling a flow of coolant fluid to maintain a temperature in the loop reactor at a preset point. The temperature in the loop reactor may be maintained at a preset point by using a coolant fluid flow controller and valve unit having a substantially linear response over the normal operating range of the controller and valve unit. The normal operating range of the controller and valve unit may be sufficient to provide a flow range not limiting to the throughput of the loop reactor.
