Abstract

The present invention relates to an initiator modified polyacidic polymer having a covalently bonded initiator compound, and to a dental resin-modified glass ionomer composition comprising this polyacidic polymer. Furthermore, the present invention relates to a use of the initiator modified polyacidic polymer for the preparation of a dental composition.The covalently bonded initiator compound of the initiator modified polyacidic polymer may be any compound of a redox initiator system, a photoinitiator system, for example a Norrish type I or II photoinitiator, an electron donor component, a sensitizer component or a coinitiator component.
