Abstract

Processes for continuously producing a polymer polyol (“PMPO”). The process includes free-radically polymerizing an ethylenically unsaturated monomer composition in the presence of a base polyol, in which the polymerizing occurs in a continuous stirred tank reactor (“CSTR”) that has an external recirculation loop comprising a pump and a heat exchanger arranged in series with respect to each other. A stream of the reactor contents is (i) continuously removed from the reactor, (ii) then continuously flows through the pump and the heat exchanger, and (iv) then continuously returns to the CSTR. A ratio of reactor system residence time to recirculation loop residence time is 10 to 93.
