Patent abstract
A method for controlling resin properties during the production of polyolefins is provided. The method utilizes coordinated manipulation of reaction temperature in combination with a secondary process variable to control resin flow properties to rapidly respond to manufacturing upsets or specification changes to minimize off-grade or transition polymer material when moving from one polymer grade to another, or during a disturbance in a steady state production.
