Beschreibung
Zusammenfassung:	A self-healing polyurethane, a polyol for use in the polyurethane, and the use of the polyol and/or polyurethane in coatings, elastomers, composites, adhesives and/or sealants is described, where the polyurethane is capable of exhibiting self-healing which results in recovery of a proportion of one or more physical parameters. The self-healing polyurethane is the reaction product of reactants comprising a polyol, a polyisocyanate; and optionally, a chain extender, where the polyol comprises at least one dimer fatty residue; at least one carbonate group; and at least two hydroxyl end groups.
