A method of obtaining compositions based on poly (2-propenal, 2-propenoic acid), comprising the following stages: dissolving poly (2-propenal, 2-propenoic acid) in an aqueous base, adding an organic compound containing one or more hydrophobic groups and subsequent acidification solution; the interaction between the hydrophobic groups of the organic compound and poly (2-propenal, 2-propenoic acid) eliminates the formation of a precipitate of poly (2-propenal, 2-propenoic acid), which occurs at pH≥5.5, and therefore, the solution is stable in a wide range of pH. |
