Abstract: Process for producing aqueous polyacrylamide solutions by polymerizing an aqueous solution comprising at least acrylamide obtained by hydrolyzing acrylonitrile in water in the presence of a biocatalyst capable of converting acrylonitrile to 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 aqueous polyacrylamide gel furthermore comprises at least one stabilizer for prevention of polymer degradation.
