A reaction resin mortar curable by frontal polymerization is described, comprising at least one radically polymerizable compound (a), at least one thiol-functionalized compound (b) and at least one polymerization initiator (c), wherein the weight ratio of the at least one radically polymerizable compound (a) and the at least one thiol-functionalized compound (b) is in the range of 10:1 to 2:1 and wherein the polymerization initiator (c) is selected from compounds which can be thermally activated and/or thermally released at a temperature of above 30° C. and/or ammonium persulfates which are formed in-situ from at least one organically substituted ammonium salt and at least one inorganic persulfate as well as a method for fixing anchor rods, rebars or the like in bore holes using the reaction resin mortar.
A reaction resin mortar curable by frontal polymerization, comprising at least one radically polymerizable compound (a), at least one thiol-functionalized compound (b) and at least one polymerization initiator (c), wherein the weight ratio of the at least one radically polymerizable compound (a) and the least one thiol-functionalized compound (b) is in the range of 10:1 to 2:1 and wherein the polymerization initiator (c) is selected from compounds which can be thermally released at a temperature of 30° C. and/or ammonium persulfates which are formed in-situ from at least one organically substituted ammonium salt and at least one inorganic persulfate.
A method for fixing anchor rods, rebars or the like in bore holes of different subgrades, wherein the reaction resin mortar according to at least one of the preceding claims is introduced into the bore hole, the anchor rod, the rebar or the like are inserted and the frontal polymerization is triggered by heating the reaction resin mortar to a temperature above the reaction temperature of the polymerization initiator or of the polymerization accelerator.
