NOVELTY - Adhesive bead comprises a shell and core where the core comprises one or more polymerizable monomers and the shell comprises a polymer of the same one more polymerizable monomers, where the polymer is selected from one or more of polyacrylates, polycyanoacrylates, epoxies, silicones and polyurethanes.    USE - The adhesive bead is useful for preparing composition, composite, and article, e.g. fastener, medical device, construction material or construction plenum (all claimed). It can also be used in coatings, construction materials, thread locks, herbicides, pesticides, electronics and viewable parts, fiber optics, optical devices, solar cells and collectors, medical and cosmetic applications, and craft projects.    ADVANTAGE - When produced as microspheres with sub-millimeter diameters, the adhesive beads advantageously exhibit low density, improved dimensional stability, increased impact strength, smoother surface finish, greater thermal insulation, easier machinability, faster cycle times, and cost savings. The relatively low surface area of the beads, when formulated as microspheres, allows for higher solids loading and lower impact on viscosity and flow characteristics of compositions containing the adhesive beads. Other advantages of the beads include the simplicity of a single polymeric system; and there is no need to match the shell polymer to the adhesive polymer as both parts are the same. The processes for making the beads is also simplified and does not require additional toxic chemicals, as the processes may be carried out in water with little to no effluent in need of treatment upon completion of the processes. The processes are flexible, allowing one to readily adjust the size of the beads, the monomer composition, the shell thickness and other characteristics such as heat and/or water resistance. Finally, the beads may be prepared inexpensively as additional chemicals for the shell are not needed and standard chemical mixing equipment can be used.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a composition comprising the bead and a liquid, a paint, or a coating;    (2) an article comprising the bead, where the article is selected from a fastener, a medical device, a construction material or a construction plenum;    (3) a composite comprising a matrix polymer and the beads; and    (4) a method of preparing the bead which involves adding a base to heterogeneous mixture comprising one or more cyanoacrylate monomers and/or oligomers and a fluid in which the one or more cyanoacrylate monomers are substantially insoluble, and forming a bead comprising a shell surrounding a core, where the core comprises the cyanoacrylate monomers, and the shell comprises a polymer of the same cyanoacrylate monomers; or a method of preparing the bead which involves forming droplets of an cyanoacrylate monomer and/or oligomer in air, the droplets optionally comprising an acid, and coating the droplets with an alkaline aqueous solution to form a bead comprising a polymeric shell surrounding a core, where the core comprises the cyanoacrylate monomer; or a method of preparing the bead which involves extruding one or more cyanoacrylate monomers into an alkaline solution and adjusting the pH to below 7 to form an extrudate comprising a shell of polycyanoacrylate surrounding a core, where the core comprises the one or more of the cyanoacrylate monomers.
