Abstract
This invention relates to a blocked process for producing polymers of high and low molecular weights utilizing the same polymer separator. The separator is operated in a different mode depending on the molecular weight of the polymer being produced such that the separation system is operated in flash mode for the separation of low molecular weight polymers and operated in lower critical solution temperature (LCST) mode for the separation of high molecular weight polymers.
