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.
