Abstract: Process and a plant for making polyacrylamides by polymerizing an aqueous solution comprising at least acrylamide and acrylic acid or salts thereof in the presence of initiators for radical polymerization under adiabatic conditions, wherein acrylamide and acrylic acid are stored at the site of the plant as dilute aqueous solutions in pressure-resistant tanks and also the monomer mixing vessel and the polymerization vessel are pressure-resistant. The combination of using diluted monomer solutions and pressure-resistant tanks ensures that even in case of an unintended and uncontrolled polymerization, said vessels don't burst and there is no spill out of the plant to the environment.
