摘要：
The invention relates to a hardenable multi-part liquid acrylic composition. The composition comprises a storage stable liquid first part, a storage stable liquid second part and optionally, a third or further liquid parts. The parts are operable to form a cement which hardens to a solid upon mixing of the parts together. The composition comprises an acrylic monomer component, an initiator component,acrylic polymer particles and a radiopacifying filler. The initiator component is present in an amount effective topolymerize the acrylic monomer component upon being mixed and/or activated therewith. At least some of the radiopacifying filler is encapsulated within and/or adsorbed on the acrylic polymer particles in a liquid part. The invention extends to an at least twin barreled syringe or caulking gun accommodating the multi-part composition, a method of producing the multi-part composition, a composition for use as bone cement composition or in dental repairs, a liquid composition comprising a first sub-population of emulsion or non-emulsion polymerized acrylic polymer particles and radiopacifying filler encapsulated and/or adsorbed in the first sub-population of acrylic polymer particles and bone cement compositions or dental compositions.
