Abstract
The present invention pertains to a process for preparing clusters of infusible, inherently tacky, elastomeric, solvent-insoluble, solvent-dispersible polymeric microparticles by aqueous emulsion polymerization. The invention also pertains to an adhesive comprising the polymeric microparticles and to a repeatedly reusable pressure sensitive sheet material having the elastomeric microparticles coated thereon.
