A composition of matter represented by structure (I), wherein n is 2 to 6; R 1 and R7 are each independently hydrogen, hydrocarbyl groups, hydroxyhydrocarb yl groups, alkoxyhydrocarbyl groups, aminohydrocarbyl groups, aminohydrocarbyl groups wherein the amine nitrogen is substituted by (II), alkoxy-terminated or amine-terminated polyether groups, or a mixture thereof; R2 to R6 are each independently hydrogen or hydrocarbyl groups, and each X is independently hydrogen, metal, ammonium or substituted ammonium. This compound is the reaction product of an alkylenediamine, each amino thereof being a primary o r secondary amino group with at least two equivalents of an acrylamidoalkanesulphonic acid or a salt thereof, wherein each amine nitroge n atom of said alkylenediamine is reacted with a single molecule of the acrylamidoalkanesulphonic acid or salt thereof and provides a useful surfactant or hydrotrope.
