摘要
A polymerizable polymethylmethacrylate bone cement, in which the initial viscosity of the cement dough can be controlled. The polymerizable bone cement composition comprises a monomer for radical polymerization, a powdered polymethylmethacrylate-co-polymer soluble in the monomer or a mixture comprising polymethylmethacrylate-co-polymers, a polymerization initiator, and a radiopaquer, wherein the powdered polymethylmethacrylate-co-polymer comprises at least one particulate polymethylmethacrylate-co-polymer having a molar mass of more than or equal to 200,000 g/mol, and the polymethylmethacrylate-co-polymer is obtainable by polymerization of a mixture of 90.0% or more by weight methylmethacrylate and 10.0% or less by weight of one or more comonomers, wherein the weight ratio of component A comprising the polymethylmethacrylate-co-polymer, radiopaquer, and polymerization initiator, and component B comprising a monomer for radical polymerization, stabilizer, and polymerization accelerator, is approximately 2.0 to 3.4 to 1.0, for controlling the initial viscosity of the bone cement dough formed by mixing components A and B.
