The invention relates to a hardenable multi-component acrylic composition. The composition has at least two components which, when mixed together, react with each other to gradually harden, thereby forming a solid adhesive such as a bone adhesive. The beads in the first component include: an acrylic bead polymer core, which is produced by suspension polymerization, and has a Tg> 70 ° C; and an emulsion polymerized acrylic particle, which at least partially coats the acrylic bead polymer core. surface. The particles can form a porous coalesced network. The bone adhesive composition includes a first component and a liquid second component, and optionally other components. The components can be manipulated to form an adhesive that hardens into a solid mass after the components are mixed together. The composition further includes an acrylic monomer component and an initiator component in the second component. A method of producing coated beads of a hardenable multi-component composition and a solid binder is also described. |
