The viscoelastic properties of polymer chains with a few number of pairwise associating functional groups are studied as a function of polymer molecular weight, degree of substitution and polymer concentration. As a model system, polybutadienes of narrow molecular weight distribution are used as starting materials. These polymer chains are modified by introducing few 1,2,4‐triazolidine‐3,5‐dione (urazole) groups U. These form defined dimeric hydrogen bond complexes U + U → U 2 .
