Abstract

A description is given of the use of compounds having n 2-oxo-1,3-dioxolane-4-carboxamide units as a reactive component in 2-component adhesives, especially for preparing hydroxypolyurethanes or hydroxypolycarbonates for adhesives applications, where n is a number greater than or equal to 2. A description is also given of corresponding two-component adhesives and adhesive bonding methods. Employed preferably as a second component of the two-component adhesive is a polyfunctional curing agent compound which is preferably selected from polyamines which have two or more amine groups and polyols which have two or more alcoholic hydroxyl groups.
