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.

Abstract: A dental composition comprising a polymerizable acidic compound of the following formula (I): wherein R1 which may be the same or different when more than one R1 is present, represents a hydrogen atom or a methyl group; R2 which may be the same or different when more than one R2 is present, represents a hydrogen atom, a straight-chain or branched C1-6 alkyl group, a C3-8 cycloalkyl group or a straight-chain or branched C2-6 alkenyl group; R3 which may be the same or different when more than one R3 is present, represents a monovalent organic moiety substituted by a group selected from —COOM, —PO3M, —O—PO3M2 and —SO3M, wherein M independently represents a hydrogen atom or a metal atom; or R2 and R3 form together a divalent organic moiety substituted by a group selected from —COOM, —PO3M, —O—PO3M2 and —SO3M, wherein M independently represents a hydrogen atom or a metal atom; L represents a (m+n+1)-valent organic linker group; X represents a hydrogen atom or a group selected from —COOM, —PO3M, —O—PO3M2 or —SO3M, wherein M independently is a hydrogen atom or a metal atom; m is an integer of 0 to 6; n is an integer of 0 to 6; wherein (m+n) is at least 2; provided that when n is 0, then X cannot be a hydrogen atom.

Abstract: An aqueous dental glass ionomer composition comprising (A) a reactive particulate glass, (B) a water-soluble polymer comprising acidic groups, which is reactive with the particulate glass in a cement reaction, (C) a water-soluble, hydrolysis-stable monomer having a single polymerizable double bond and optionally a carboxylic acid group or hydroxyl group; (D) a water-soluble, hydrolysis-stable polymerizable crosslinker having at least two polymerizable carbon-carbon double bonds; and (E) a polymerization initiator system.
