The invention relates to a specific polyurethane prepolymer (PP2) comprising at least two (2-oxo-1,3-dioxolan-4-yl)methyl-carbamate end groups and having low viscosity, to the method for the production thereof, and to the use of same in the production of an adhesive composition. The invention also relates to a multi-component system comprising, as a first component (A), a composition comprising at least one such polyurethane prepolymer and, as a second component (B), a composition comprising at least one hardener having at least two primary amine groups (-NH2) (B1). The invention further relates to a method for assembling materials, using the polyurethane prepolymer (PP2) according to the invention. |
