摘要： 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.

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;
(D) a polymerization initiator system; and
(E) a polymerizable hydrolysis-stable crosslinker having at least two polymerizable carbon-carbon double bonds.
