Preparation and characterization of acid free acrylic pressure sensitive adhesive with high re- fractive index for optically clear adhesive

摘要

Acrylic PSA was synthesized by solvent polymerization for giving optical property which is acid-free and high refractive index property through monomers having high refractive index without acidic functionality. Then comparison of physical property between acidic PSA and acid free PSA was carried out. In case of probe tack, it was good but it is considered that more enough curing system is needed for more increased cohesion between molecules.
