Optical properties and UV-curing behaviors of optically clear semi-interpenetrated structured acrylic pressure sensitive adhesives

Acrylic pressure-sensitive adhesives (PSAs) with different side-chain lengths in the co-monomer were synthesized. This study employed semi-interpenetrated structured polymer networks using UV-curing with a hexafunctional monomer, dipentaerythritol hexacrylate (DPHA). The optical properties of the ac...

Zusammenfassung:	Acrylic pressure-sensitive adhesives (PSAs) with different side-chain lengths in the co-monomer were synthesized. This study employed semi-interpenetrated structured polymer networks using UV-curing with a hexafunctional monomer, dipentaerythritol hexacrylate (DPHA). The optical properties of the acrylic PSAs were examined by UV-visible spectroscopy and a prism coupler. ARES was used to characterize the viscoelastic properties of the acrylic PSAs. Adhesion performance was conducted by the peel strength and probe tack tests. Also UV-curing behavior of the acrylic PSAs was investigated by FTIR.
