Claim Text:
1. A one-component polymethylmethacrylate bone cement paste consisting of (i) at least one methacrylate monomer selected from the group consisting of butan-1,3-diol-dimethacrylate, butan-1,4-diol-dimethacrylate, and hexan-1,6-diol-dimethacrylate; (ii) at least one polymer that is soluble in the methacrylate monomer; (iii) at least one particulate polymer selected from the group consisting of cross-linked poly-methylmethacrylate and cross-linked poly-methylmethacrylate-co-methylacrylate, wherein the particulate polymer is insoluble in the methacrylate monomer and having a particle size of less than 500 μm; (v) at least one electrically conductive radio-opaquer; (vi) optionally at least one additional radio-opaquer; (vii) optionally at least one pharmaceutical agent; and (viii) optionally at least one biocompatible elastomer that is particulate or soluble in the methacrylate monomer/methacrylate monomers; wherein the ratio of said at least one methacrylate monomer to soluble polymer to particulate insoluble polymer to radical initiator to electrically conductive radio-opaquer is 25-50:2-35:40-70:0.5-4.0:2.0-20 based on the weight of the paste.
