摘要： A pasty two-component polymethacrylate bone cement comprising a pasty component A, containing AI 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; and AV at least one aromatic amine accelerator; and a pasty component B, containing BI 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.

摘要： A storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge with a cylindrical interior, a cartridge head that closes one end of the tubular cartridge, a partition wall axially disposed in the cylindrical interior and dividing the cylindrical interior into two spatially separate cavities, the first cavity including a first pasty cement component and the second cavity including a second pasty cement component, two delivery plungers disposed movably in the two cavities and connected via a connecting means, wherein a wedge or cone having a cutting edge on the front side thereof facing the cartridge head is disposed on the connecting means, such that said cutting edge cuts open the partition wall when the delivery pistons are advanced towards the cartridge head and the wedge or cone presses the cut open parts of the partition wall towards the inner wall of the cartridge.
