摘要: Acidic monomer according to Formula I: in which A is a linear or branched aliphatic C1-C18-hydrocarbon group, which can be interrupted by one or more —O—, —S—, —CO—O—, —O—CO—NH—, —HN—CO—NH— or —CO—NR1—; R1 is H or a C1-C6 alkyl group; X is absent or is a linear or branched aliphatic C1-C10 hydrocarbon group, which can be interrupted by one or more —O—, —S—, —CO—O—, —O—CO—NH—, —HN—CO—NH— or —CO—NR2—; R2 is H or a C1-C6 alkyl group; PG is a radically polymerizable group, preferably vinyl, allyl, CH2═CR3—CO—Y— or R4O—CO—C(═CH2)—CH2—Y—; Y═O or NR5 or is absent; R3 is H or CH3; R4 is H or a C1-C7 alkyl group; R5 is H or a C1-C7 alkyl group; n is 1, 2, 3 or 4; m=1 or 2; p=1, 2 or 3; and q=1, 2 or 3. The monomers are particularly suitable as components of dental material.

摘要: Dental material which contains at least one vinylcyclopropane of the general formulae I, in which A, B independently of each other are in each case OH or COOH; X, Y independently of each other are in each case O or NH; R1, R2 independently of each other are in each case H or an aliphatic linear or branched C1-C10 hydrocarbon radical which can be interrupted by O, S or an ester group; and n, m independently of each other are in each case 0, 1 or 2, wherein, if X=Y=O, R1≠H and R2≠H, n+m≧1. The vinylcyclopropanes are characterized by a low shrinkage and a high reactivity on radical polymerization and are suitable in particular for the preparation of dental materials.
