ABSTRACT:
Inherently tacky infusible pressure-sensitive adhesive microspheres are prepared by polymerizing at least one monomer which when polymerized will form a pressure-sensitive adhesive having a glass transition temperature less than abotu -20.degree. C. in an organic medium in which the monomer is substantially insoluble and in the presence of a surfactant and a suspension stabilizer which are soluble in the organic medium and substantially insoluble in the monomer under conditions of shear sufficient to form suspended particles of a size less than 200 microns. A monomer soluble initiator is preferably employed. The preferred media are ethylene glycol and glycerol and the preferred monomers are 2-ethyl hexyl acrylate and methacrylic acid.
