     The possibility of initiation of acrylamide and acrylic acid polymerization in acid solution contacting with metal surfaces has been studied. The acrylamide polymerization takes place effectively in the calorimeter aluminium cells or at addition the metal pieces (Mg, AL) in the solution already at the room temperature. The maximum value of polymerization rate is up to 2 wt%/min. There was observed temporary delay of beginning of polymerization caused by dissolving of oxide film on the aluminium surface. The initiation rate of acrylamide polymerization was measured by the chemical inhibitor method. The quadratic termination of the propagating chains was determined and kp/ko0.5 value was found to be close to the known values. The activation effective energy of polymerization process was determined.
