COMPOSITE PRESSURE SENSITIVE ADHESIVE MICROSPHERE

摘要

Composite pressure sensitive adhesive microspheres are provided comprising two or more water insoluble polymers that are mixed wholly within the boundaries of polymeric microspheres. The range of monomers and polymers are chosen to tailor the properties of the composite pressure sensitive adhesive microspheres for specific performance and/or application requirements. Any polymer that can be dissolved into a solvent monomer or mixture of solvent monomers can be used to prepare the composite pressure sensitive adhesive microspheres. Pressure sensitive adhesive microspheres according to this invention can be prepared using free radical suspension polymerization.
