| titleOfInvention | Dental composition |
| abstract | Dental composite comprising n(i) a polymerizable composition obtainable by reacting a mixture comprising: n(a) x equivalents of one or more compounds of the following formula (I): nwherein nL' is an (I+1)-valent hydrocarbon group which may contain in its backbone 1 to 3 heteroatoms selected from oxygen atoms and sulfur atoms and which may be substituted by one or more hydroxyl groups or groups -COOL" wherein L" is a polymerizable moiety; nI is an integer of from 1 to 3; n(b) y equivalents of one or more compounds of the following formula (IIa), (IIb) and/or (IIc): nwherein nn nis an integer of from 1 to 3, nY nmay be present or absent, and when present represents a carbonyl group; nY' nindependently may be present or absent, represents a carbonyl group; nR m nwhich may be the same or different represent 1 to 3 substituents selected from halogen atoms, alkyl groups, and alkoxy groups, or wherein two R m form together with the carbon atoms of the ring to which they are bonded an annelated aromatic ring; and n(c) z equivalents of one or more compounds of the following formula (III): nwherein nR 1 nis a hydrogen atom or an alkyl group; nk nis an integer of from 1 to 3, whereby nwhen k is 1, 2 or 3, then L is a (k+1)-valent hydrocarbon group which may contain 1 to 3 heteroatoms selected from oxygen atoms and sulfur atoms, and X is a carboxylic acid group, or a hydroxyl group bonded to an aromatic ring forming part of L; or nwherein 0.05 ¤ x/y ¤ 0.66, and 2y - f x ¤ z ¤ 1.5(2y - f x), nwherein x, y, and z are the molar equivalents of components (a), (b) and (c) and f is the mean acid functionality of component (a) : f ¾ = l = 1 3 x l x ¢ l + 1 wherein I is as defined in formula (I); and optionally reacting the hydroxyl groups and/or carboxylic acid groups on L' of the reaction product of the mixture with a compound having a polymerizable double bond; and n(ii) a particulate filler. |
