What are described are compounds having two or more exovinylene cyclocarbonate units, wherein the exovinylene cyclocarbonate units are bonded to one another via at least one organic, siloxane-free connecting group which is not bonded directly to the exovinylene double bonds, excluding connecting groups formed by polymerization of (meth)acrylic monomers. The connecting group preferably has at least one acetal group. Also described are a process for preparing the compounds, two-component binders comprising the compounds, and uses of the compounds.
