TACKY MICROSPHERES HAVING PENDANT HYDROPHILIC POLYMERIC OR OLIGOMERIC MOIETIES. |
摘要 |
<p>The invention provides inherently tacky, polymeric, organic, solvent-insoluble, solvent dispersible, elastomeric, pressure sensitive adhesive microspheres having pendant hydrophilic polymeric or oligomeric moieties having a degree of polymerization greater than or equal to 2. The microspheres which are sterically stabilized can offer enhanced stability against coagulation caused by alkali, alkali salts, polyelectrolytes and repeated freeze/thaw cycles. The present invention also provides pressure-sensitive adhesives comprising these microspheres including aerosol spray PSAs, coated sheet materials prepared therefrom, and method of making the microspheres.</p> |
