A hardenable multi-part acrylic composition
A hardenable multi-part acrylic composition having at least two parts that react upon mixing to form a cement, such as bone cement, which hardens to a solid is described that includes storage stable liquid first and second parts, and optionally, further liquid parts. The parts react upon mixing to form a cement that hardens to a solid. The composition includes an acrylic monomer component and an initiator component in an amount effective to polymerize the acrylic monomer component when mixed and/or activated with it. The liquid first part comprises an aqueous dispersionof acrylic polymer particles and acrylic polymer beads. The polymer beads are at an equilibrium water content with the aqueous phase of the dispersion that generally has a viscosity between 10 and 10,000 centipoise. A twin barrelled syringe, caulking gun or other cement mixing and delivery device and a method of producing the composition are also described.
