A hardenable two part acrylic composition is described for the treatment of human or animal bone is described. The composition comprises a storage stable liquid first part and a storage stable liquid second part which react with each other upon mixing to form a cement which hardens. The composition further comprises an acrylic monomer component and an initiator component in an amount effective to polymerize the monomer component. The monomer component and the initiator component are generally located in separate parts of the two part composition so that the monomer component is storage stable. The liquid first part comprises emulsion polymerized acrylic polymer particles in a liquid carrier. A method of producing a hardenable two part acrylic composition is also described. The composition is particularly useful in a syringe or caulking gun having at least two barrels.
A hardenable two part acrylic composition comprising a storage stable liquid first part and a storage stable liquid second part which react with each other upon mixing to form a cement which hardens, the composition further comprising an acrylic monomer component and an initiator component in an amount effective to polymerize the monomer component, wherein the said monomer component and the said initiator component are located in separate parts of the said two part composition so that the monomer component is storage stable wherein the liquid first part comprises emulsion polymerized acrylic polymer particles in a liquid carrier and initiator and the second part comprises acrylic monomer and accelerator.
A hardenable two part acrylic composition comprising a storage stable liquid first part and a storage stable liquid second part which react with each other upon mixing to form a cement which hardens, the composition further comprising an acrylic monomer component and an initiator component in an amount effective to polymerize the monomer component, wherein the liquid first part comprises emulsion polymerized acrylic polymer particles in a liquid carrier and initiator and the second part comprises acrylic monomer and accelerator.
A hardenable two part acrylic composition comprising a storage stable liquid first part and a storage stable liquid second part which react with each other upon mixing to form a cement which hardens, the composition further comprising an acrylic monomer component and an initiator component in an amount effective to polymerize the monomer component, wherein the liquid first part comprises in a liquid carrier a first population of emulsion polymerized acrylic polymer particles and a second population of emulsion polymerised acrylic polymer particles having different z-average particle size's from the first emulsion polymerised acrylic polymer particles.
A method of producing a hardenable two part acrylic composition comprising a storage stable liquid first part and a storage stable liquid second part which react with each other upon mixing to form a cement which hardens to a solid, comprising the steps of:
A liquid composition comprising emulsion polymerized acrylic polymer particles, optionally, mixed with at least one further type of non-emulsion polymerized acrylic particles, and wherein there is a polymerization initiator in the liquid composition at a level sufficient to cause the liquid composition to harden upon contact with a reactive monomer liquid.
