<p>Novel compositions are provided comprising (A) high-molecular anions from the dissociation of a part or the whole of the carboxylic group of a conjugated diene-maleic acid derivative copolymer with repeating units represented by the formulae wherein R represents a conjugated diene unit in the copolymer, R' and R" each represent hydrogen or an organic radical having from 1 to 18 carbon atoms and p and q are an integer representing the number of the respective recurring units in the molecules; (B) one or more cations of alkali metal cations selected from the group consisting of Na+, K+ and Li+ and quaternary ammonium cations represented by the formula R1R2?R3R4 wherein R1, R2, R3, and R4 each are selected from the group consisting of hydrogen, alkyl radical of from 1 to 18 carbon atoms, cycloalkyl radical and aryl radical; (C) Mg2+; (D) anions of magnesium compound(s) or alkali metal compound(s) represented by Xn- wherein n is an integer 1 or 2; and (E) water. These compositions are useful as water soluble adhesives, fire extinguishing agents, thickeners, binders, coating agents, or textile printing agents in that they are reversibly liquid at lower temperatures and solid at higher temperatures.</p> |
