Abstract

See full text

A self-restoring polyurethane-based polymer obtained by polymerization of a composition containing an aromatic disulfide diol represented by Chemical Formula, HO—Ar1—S—S—Ar2—OH, an alicyclic polyisocyanate, and a polyol. Ar1 and Ar2 each are independently a substituted or unsubstituted C6-C30 arylene group. The composition satisfies Equation, 0.1≤M[disulfide]/M[OH]. M[disulfide] is a total mole number of the aromatic disulfide diol in the composition, and M[OH] is a total mole number of the aromatic disulfide diol and the polyol in the composition.
