Claims
- 1. The vinylcyclopropane derivative according to the formula: ##STR12## in which A is --(--Y--CO--C(.dbd.CH.sub.2)R.sup.4).sub.m or --C(.dbd.CH.sub.2)CO--O--C.sub.1-4 -alkyl;
- U, X stand for CO, COO or CONH;
- Y, Z stand for O or NH or are absent, but Y and Z cannot be absent at the same time when A is --(--Y--CO--C(.dbd.CH.sub.2)R.sup.4).sub.m ;
- n, m stand for an integer from 0 to 4, but n and m are not 0 at the same time;
- R.sup.1 is H, CH.sub.3 or Cl;
- R.sup.2, R.sup.3 stand for H, a C.sub.1 - to C.sub.10 -alkyl or alkylene radical, which can be interrupted by O, S or NH, for a C.sub.6 - to C.sub.14 -aryl or arylene, C.sub.7 - to C.sub.14 -alkylaryl or alkylarylene or a C.sub.5 - to C.sub.8 -cycloalkyl or cycloalkylene; and
- R.sup.4 is H or a C.sub.1 - to C.sub.10 -alkyl.
- 2. The vinylcyclopropane derivative according to claim 1, wherein
- U, X stand for COO or CONH,
- Y, Z stand for O or are absent,
- n, m stand for an integer from 0 to 2,
- R.sup.1 stands for H,
- R.sup.2, R.sup.3 stand for a C.sub.1 - to C.sub.6 -alkyl or alkylene radical, C.sub.6 -aryl or arylene or a C.sub.6 -cycloalkyl or cyclo-alkylene radical; and/or
- R.sup.4 is H or a C.sub.1 -C.sub.3 -alkyl radical.
- 3. The vinylcyclopropane derivative according to claim 2, wherein
- R.sup.2 and R.sup.3 are the same;
- R.sup.4 is H;
- n, m are in each case 1 and
- U, X stand for COO or CONNH,
- or
- R.sup.2 and R.sup.3 are different;
- N is 0,
- M is 1 or 2,
- Z is absent,
- Y stands for O and
- R.sup.4 stands for H.
- 4. A process for the production of vinylcyclopropane derivatives according to claim 1, wherein a vinylcyclopropane derivative of formula I, in which R.sup.2 is a C.sub.1 - to C.sub.10 -alkyl or phenyl radical, is reacted with a (meth)acrylic acid derivative, having, as a leaving group, OH or halogen, to give the intermediate stage (IV) or the final stage (V), and (IV) is optionally converted with a further (meth)-acrylic acid derivative (III), which can be identical with the first (meth)acrylic acid derivative, into the desired vinylcyclopropane derivative of formula I.
- 5. A dental material containing
- (a) I to 99 wt.-% of a vinylcyclopropane derivative according to claim 1,
- (b) 0 to 80 wt.-% of another radically polymerizable polymer,
- (c) 0.01 to 5 wt.-% of an initiator for the radical polymerization,
- (d) 0 to 90 wt.-% of a filler.
- 6. A dental material according to claim 5, containing
- (a) 5 to 70 wt.-% of the vinylcyclopropane derivative,
- (b) 0 to 60 wt.-% of another radically polymerizable polymer, and/or
- (c) 0.1 to 2 wt.-% of an initiator for the radical polymerization.
- 7. A dental material according to claim 5, containing 0 to 20 wt.-% of an adhesive, 20 to 60 wt.-% of a cement or 60 to 85 wt.-% of a filling composite filler.
- 8. A dental adhesive comprising the vinylcyclopropane derivative of claim 1.
- 9. A dental cement comprising the vinylcyclopropane derivative of claim 1.
- 10. A dental composite comprising the vinylcyclopropane derivative of claim 1.
- 11. A dental moulding comprising the vinylcyclopropane derivative of claim 1.
