21. A microencapsulated adhesive composition produced by
microencapsulating a mixture containing as a major component an alkyl acrylate or
methacrylate monomer, or a mixture thereof, and a free radical initiator; followed
by heating said microencapsulated monomer and initiator for a time and at a
temperature sufficient to cause said monomer to polymerize inside said
microcapsules, thereby forming an adhesive that is initially non-tacky but exhibits
tacky properties upon application of external forces.
