PROBLEM TO BE SOLVED: To provide a curable composition that is useful for a variety of applications (for example, adhesives, sealants, surface coatings) and has improved thixotropy and excellent sag resistance. SOLUTION: This composition comprises (a) a polymer containing pendant and/or functional groups selected from the group consisting of carbamate, urethane, and/or amide functional groups; and (b) a rheology modifier comprising the reaction products of an amine and an isocyanate; and, optionally a polymer which is different from the polymer (a) which contains carbamate, urethane, and/or amide functional groups. Also disclosed are curable composition composed of the compositions described above which further comprises (c) a curing agent having functional groups reactive with the functional groups of the polymer (a).
