A polymethylmethacrylate bone cement is produced by a method. The method comprises the steps of a) providing a cement powder comprising: at least one particulate polymethylmethacrylate or polymethylmethacrylate-copolymer wherein the at least one particulate polymethylmethacrylate or polymethylmethacrylate-copolymer have a particle size of less than 100 μm； an initiator； and at least one particulate or fibrous additive that is insoluble in methylmethacrylate, wherein the additive has an absorption capacity at room temperature of more than or equal to 0.6 g methylmethacrylate per gram of additive； b) providing a monomer solution comprising: at least one methylmethacrylate； and at least one activator； and c) mixing the cement powder and the monomer solution, characterised in that the mixing takes place without the application of shearing forces.
