A biomass-based isosorbide acrylate (ISA) was synthesized in a one-pot reaction at low temperature with a quite slow dropwise technique using a syringe pump. Using the ISA monomer, UV-cured transparent acrylic pressure-sensitive adhesives (PSAs) composed of semi-interpenetrating networks were prepared. The effect of ISA on the adhesion performance of the resulting acrylic PSAs was investigated by changing the ISA content, while fixing the mole ratio between 2-ethylhexyl acrylate and 2-hydroxyethyl acrylate in the PSAs. The prepared acrylic PSAs, with ISA content ranging from 3.2 to 14.3 mol%, were evaluated in terms of 180 ∘ peel strength, probe tack, static shear testing and optical properties. Increasing the ISA content in the acrylic PSAs improved the adhesion properties, such as 180 ∘ peel strength (0.25-0.32 N/25 mm), shear holding power (0.086-0.023 mm) and probe tack (1.21-2.26 N). Dynamic mechanical analysis indicated that ISA is a good candidate monomer, playing the role of adhesion promoter and hard monomer in the acrylic PSAs.
