    摘要： A redox curing dental composition comprising:
    (a) one or more compounds having a radical polymerizable carbon-carbon double bond;
    (b) a redox initiator system comprising
    (i) a reducing agent which is a compound of the following formula (I):

    wherein
    R 1 and R 2
    which may be the same or different, independently represent a C 1-18 hydrocarbyl group, or R 1 and R 2 form together with the silicon atom to which they are bonded a 3 to 8-membered silicon-containing alicyclic ring, which groups R 1 and/or R 2 may be substituted with one to three substituents selected from the group consisting of a C 1-6 alkoxy group, a halogen atom, or a carboxylic acid group; and
    (ii) an oxidizing agent adapted to oxidize the reducing agent of formula (I) in the absence of light for generating a radical capable of initiating radical polymerization of the one or more compounds having a radical polymerizable carbon-carbon double bond.

    摘要： The present invention relates to an aqueous dental glass ionomer composition comprising
    (A) a reactive particulate glass,
    (B) a water-soluble, polymerizable polymer comprising acidic groups, which is reactive with the particulate glass in a cement reaction, whereby the polymerizable polymer has a polymer backbone and hydrolysis-stable pendant groups having one or more polymerizable carbon-carbon double bonds, wherein the polymerizable polymer is obtainable by a process comprising
    a) a step of copolymerizing a mixture comprising
    (i) a first copolymerizable monomer comprising at least one optionally protected carboxylic acid group and a first polymerizable organic moiety, and
    (ii) a second copolymerizable monomer comprising one or more optionally protected primary and/or secondary amino groups and a second polymerizable organic moiety,
    for obtaining an amino group containing copolymer;

    b) a step of coupling to the amino group containing copolymer a compound having a polymerizable moiety and a functional group reactive with an amino group of repeating units derived from the second copolymerizable monomer in the amino group containing copolymer obtained in the first step , wherein the optionally protected amino group is deprotected, so that polymerizable pendant groups are linked to the backbone by hydrolysis-stable linking groups,
    and, optionally, a step of deprotecting the protected carboxylic acid group after step a) or step b), for obtaining a polymerizable polymer;

    (C) a hydrolysis-stable, water-soluble monomer having one polymerizable double bond and optionally a carboxylic acid group, said monomer having a molecular weight of at most 200 Da; and
    (D) a polymerization initiator system.

    摘要： 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.
