Abstract:
1. A method of treating a composition, said method comprising the steps of: providing the composition including an adduct of a conjugate base and polyethyleneimine, a component selected from the group of polyethyleneimine made under acid catalysis in water, alkoxylated polyethyleneimine intermediate, and combinations thereof, and, optionally, water remaining after the polyethyleneimine is made or water used as an accelerator to form the alkoxylated polyethyleneimine intermediate; substantially decomposing the adduct in the composition by heating the composition at a temperature of from 158 to 338° F. for a period of at least 3 hours in the absence of additional water; and stripping any water that is present in the composition to substantially remove the water from the composition prior to decomposing the adduct.
