    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: The present disclosure relates to an aqueous dental glass ionomer composition comprising a reactive particulate glass, a water-soluble, polymerizable polymer which is reactive with the particulate glass in a cement reaction, a hydrolysis-stable, water-soluble monomer having a single polymerizable double bond and optionally a carboxylic acid group or hydroxyl group; and a polymerization initiator system, wherein the polymerizable polymer is obtainable by a process comprising a step of polymerizing a mixture comprising a first polymerizable monomer comprising at least one optionally protected carboxylic acid group and a first polymerizable organic moiety, and optionally a second copolymerizable monomer comprising one or more optionally protected primary and/or secondary hydroxyl and/or amino group(s) and a second polymerizable organic moiety, for obtaining an water-soluble polymer; a step of coupling to the water-soluble polymer a compound having a olymerizable moiety and a functional group reactive with an optionally protected carboxylic acid group of repeating units derived from the first polymerizable monomer or an optionally protected hydroxyl and/or amino group of repeating units derived from the second copolymerizable monomer in the water-soluble polymer obtained in step a), wherein the optionally protected carboxylic acid group and the optionally protected hydroxyl and/or amine group are deprotected, so that polymerizable pendant groups are linked to the backbone by ester groups, urethane groups and/or amide groups, and, optionally, a step of deprotecting the protected carboxylic acid group for obtaining a polymerizable polymer.
