A pasty two-component polymethacrylate bone cement comprising a pasty component A, containingAI at least one distillable methacrylate monomer for radical polymerisation；AII at least one polymer soluble in AI；AIII at least one particulate polymer with a particle size of no more than 500 μm that is not soluble in AI；AIV at least one radical stabiliser； andAV at least one aromatic amine accelerator； and a pasty component B, containingBI dibenzoyl peroxide；BII at least one substance that is not subject to radical polymerisation and is liquid at room temperature, whereby the solubility of dibenzoyl peroxide in this substance at room temperature is less than 5.0% by weight and, whereby the weight fraction of liquid substance BII in the self-curing cement dough is less than 2.0% by weight. Also disclosed is a method for producing a self-curing bone cement dough using the pasty two-component polymethacrylate bone cement.
