ABSTRACT:
A curing agent component is described for an at least two-component mortar composition for the chemical fastening technique, containing at least one free radical-forming agent as curing agent for an organic resin component, water and at least one water-soluble, ethylenically unsaturated polyethylene glycol derivative, which can be copolymerized with the organic resin component and has a solubility in water at 25° C. of at least 10 g in 100 gram of water and has the structure given by the general formula I:in-line-formulae description="In-line Formulae" end="lead"?R2—A—O—R1  (I)in-line-formulae description="In-line Formulae" end="tail"?in which R1represents a group having the formula CH2═CH—CH2—, CH2═CH—CO—O— or CH2═C(CH3)—CO—O—, R2represents hydrogen, an alkyl group with 1 to 6 carbon atoms, a sulfonate group or a group having the formula CH2═CH—CH2—, CH2═CH—CO—O— or CH2═C(CH3)—CO—O—, and A represents a linear or branched, homopolymeric or copolymeric, optionally substituted polyoxyalkylene group. Furthermore, methods are described for producing and using the curing agent component in a two-component or multi-component mortar composition for fastening construction elements in a solid substrate.
