Dynamic viscoelastic measurements, viscosity growth function measurements at the onset of steady shear flows and dielectric measurements were carried out in a highly viscoelastic system (SEH
2B/C
10), solutions of 1-stearoylamino-3,5-bis(2-ethylhexylaminocarbonyl)benzene (SEH
2B) in
n-decane (C
10), to investigate structure and dynamics of a supramolecular polymer formed in the system via intermolecular hydrogen bonding. The SEH
2B/C
10 system showed almost the same viscoelastic and dielectric features: a single Maxwell element type viscoelasticity and single Debye-type dielectric response, over a wide concentration range as that observed in another, previously examined, supramolecular polymeric system (DO
3B/C
10) formed by N,N',N”-tris(3,7-dimethyloctyl)benzene-1,3,5- tricarboxamide in C
10 irrespective of distinctive difference in chemical structure between SEH
2B and DO
3B. These reveal that structure including macro-dipole moments and dynamics of the supramolecular polymer of SEH
2B is similar to that of the suprapolymer of DO
3B beyond the difference in their chemical structures.
