Abstract

The invention is directed to a reversible adhesive polymer composition, an electronic device, a use of a reversible adhesive polymer composition, a method for reversibly adhering at least two components within one or different electronic devices, and a method for separating elements of an electronic device for improved recyclability or repairability.The reversible adhesive polymer composition comprises polymer chains, said polymer chains comprising relative to 6 units derived from diisocyanate: at least 1 unit derived from dianhydrohexitol, at least 0.2 units derived from polyol comprising at least three hydroxyl moieties, and at least 3 blocks of oligomer diol.
