    Abstract: Process for producing aqueous polyacrylamide solutions by polymerizing an aqueous solution comprising at least acrylamide thereby obtaining an aqueous polyacrylamide gel and dissolving said aqueous polyacrylamide gel in water, wherein the manufacturing steps are allocated to two different locations A and B and the process comprises the step of transporting an aqueous polyacrylamide gel hold in a transportable polymerization unit from a location A to a location B. The transportable polymerization unit comprises a cylindrical upper part, a conical part at its lower end, feeds for the aqueous monomer solution, a closable bottom opening, and means allowing to deploy the polymerization unit in a vertical manner.
