Abstract

Low-viscosity epoxy methacrylate compounds are useful for lowering the viscosity of reactive resins and for reducing the forces for extruding a reactive-resin component containing these compounds. Furthermore, the low-viscosity epoxy methacrylate compounds are useful for chemical fastening.

First claim

1 . A compound of the general formula (1)

in which
m is a whole number greater than or equal to 2, and
B is a linear, branched or cyclic aliphatic hydrocarbon group.

2 . The compound according to claim 1 , wherein the aliphatic hydrocarbon group B is substituted.

3 . The compound according to claim 2 , wherein the aliphatic hydrocarbon group B is hydroxy-substituted.

4 . The compound according to claim 1 , wherein the aliphatic hydrocarbon group is a linear or branched C 2 -C 12 alkylene group.

5 . The compound according to claim 4 , wherein the aliphatic hydrocarbon group is a linear or branched C 2 -C 8 alkylene group.

6 . The compound according to claim 1 , wherein m is 2 or 3 and the aliphatic hydrocarbon group is a linear or branched C 2 -C 8 alkylene group.

7 . A method of construction, comprising:
incorporating the compound according to claim 1 in a reactive resin or a reactive-resin component.

8 . A method of lowering a viscosity in a reactive-resin component for construction purposes, the method comprising:
incorporating the compound of claim 1 in a reactive-resin component for construction purposes in need thereof.

9 . A method of reducing a force for extruding a reactive-resin component or a reactive-resin system, the method comprising:
incorporating the compound according to claim 1 in a reactive-resin component or a reactive-resin system in need thereof.

10 . A reactive resin, comprising:
the compound according to claim 1 , an inhibitor, an accelerator, and optionally a reactive diluent.

11 . A reactive-resin component, comprising:
the reactive resin according to claim 10 .

12 . A reactive-resin system, comprising:
the reactive-resin component according to claim 11 and a hardener component.

13 . The reactive-resin system according to claim 12 , wherein the reactive-resin component and/or the hardener component contains at least one inorganic filler and/or an inorganic additive.

14 . (canceled)

15 . (canceled)

16 . A method of construction with the reactive resin according to claim 10 , the method comprising:
combining at least the compound, the inhibitor, and the accelerator, thereby obtaining the reactive resin, and applying the reactive resin for construction.

17 . A method of construction with the reactive-resin system according to claim 12 , the method comprising:
combining the reactive-resin component and the hardener component, thereby obtaining the reactive-resin system, and applying the reactive-resin system for construction.

18 . A method for chemically fastening an anchor in a drilled hole with the reactive resin according to claim 10 , the method comprising:
combining at least the compound, the inhibitor, and the accelerator, thereby obtaining the reactive resin, and chemically fastening the anchor in the drilled hole with the reactive resin.

19 . A method for chemically fastening an anchor in a drilled hole with the reactive-resin system according to claim 12 , the method comprising:
combining the reactive-resin component and the hardener component, thereby obtaining the reactive-resin system, and chemically fastening the anchor in the drilled hole with the reactive-resin system.
