Abstract: The invention relates to a method for the transportation of a monomer composition in which a composition comprising an aqueous solution of partially or entirely neutralized acrylic acid or overneutralized acrylic acid is placed in a transport means or sent through a pipe. The method according to the invention is characterized in that it has an increased level of safety during the transportation of acrylic acid monomers, an improved quality of the resulting product, and a high degree of efficiency. The method ensures safe transport of the highly reactive acrylic acid. The amount of polymerization inhibitors added to said acrylic acid may be reduced. An additional advantage is the minimization of the formation of dimeric acrylic acid. Tempering of containers, pipes, and pipelines may be omitted.
