Abstract
A process for producing alkoxylates features a high growth ratio without the need of interim storage of a pre-polymer produced in a first reactor. The process may involve reacting a monomeric educt in the presence of a catalyst and a starting material in a first reactor equipped with a first circulation loop and thereafter passing a pre-polymer that is produced of the first circulation loop to a second reactor equipped with a second circulation loop, where a desired polymer is produced. The first reactor may comprise a smaller volume than the second reactor. The growth ratio, defined as a final batch volume of the second reactor divided by a minimum initial volume of the starting material in the first reactor, is at least 80:1.
