✦ Synopsis

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 GЉ, and dynamic loss tangent tan d, were constructed with the temperaturerate superposition principle. The probe tack and peel strength for PBA/P(VDF-HFA) blends were correlated with G and GЉ. Since the G and GЉ values increased with increasing P(VDF-HFA) content, the holding power of PBA adhesive could be advanced by blending P(VDF-HFA).
