摘要
The method of preparing a self-curing two-component powder liquid bone cement comprising a powder component consisting of polymethylmethacrylate (PMMA) particles (1) containing benzoyl peroxide (BPO) as a polymerization catalyst (2), and methylmethacrylate (MMA) as a liquid polymerizable component (3), is performed by the following two steps: A) an evacuated, inflexible chamber (4) of a syringe (11) is filled essentially completely with the PMMA particles (1) which are at least partially solvable in the MMA monomer (3) and containing the BPO (2) distributed throughout the PMMA particles (1); B) by the action of the vacuum in the interspaces between the PMMA particles (1) the said interspaces are essentially completely flooded and the said PMMA particles are completely wetted by the said MMA monomer (3) and thereby at least a surface layer (9) of said PMMA particles (1) is dissolved and the corresponding BPO (2) contained in the said dissolved surface layer (9) initiates the polymerization process in the flooded cement mixture (7) .
