Single component poly(methyl methacrylate) bone cement paste comprises (A1) at least a radical polymerizable, methacrylate monomer, (A2) at least a polymer soluble in (A1) and (A3) at least a particular polymer with a particle size of less than 500 mu m that is insoluble in (A1). Independent claims are included for: (1) hardening bone cement paste, comprising exposing the bone cement paste to a magnetic alternating field with a frequency of 500 Hz to 50 kHz and (2) hardening a paste containing at least an activatable initiator, preferably at least a radical-forming initiator or at least a thermally disintegrating radical initiator, and at least electrically conductive particles, preferably ferromagnetic particles, comprising exposing the paste to a magnetic alternating field with a frequency of 500 Hz to 50 kHz, or heating the paste by induction until the thermal decomposition of the initiators is induced.
