Abstract

The invention provides a radically polymerizable compound wherein an acid group is joined via a spacer group to a polyethyleneimine group. The polyethyleneimine group has at least one radically polymerizable group in the side chain and/or terminally. The invention relates further to a process for preparing such compounds by cationic polymerization of oxazolines, to the use of such compounds as constituents of a dental material, and to a dental material comprising the compounds of the invention.
