Poly(Butyl Acrylate)/Poly(Vinylidene Fluoride-Co-Hexafluoroacetone) Blends as Pressure-Sensitive Adhesives
The pressure-sensitive adhesive (PSA) properties and dynamic mechanical properties were measured for the poly(butyl acrylate) (PBA)/poly(vinylidene fluoride-co-hexafluoroacetone) [P(VDF-HFA)] blends. The PSA properties of PBA adhesive could be controlled by blending P(VDF-HFA). In order to investigate the relationship between PSA properties and dynamic mechanical properties for PBA/P(VDF-HFA) blends, the master curves of the dynamic mechanical properties, such as storage modulus G’, loss modulus G ", and dynamic loss tangent tan delta, were constructed with the temperature-rate superposition principle. The probe tack and peel strength for PBA/P(VDF-HFA) blends were correlated with G’ and G ". Since the G’ and G " values increased with increasing P(VDF-HFA) content, the holding power of PBA adhesive could be advanced by blending P(VDF-HFA).
