Description

Adhesion strength increases by the development of cohesive strength and interfacial adhesion. In order to evaluate the relative contribution ratio of those two factors, the tack of acrylic block copolymer was measured using a probe tack tester. For this purpose, three model adhesives were prepared: polymethylmethacrylate-block-polybutylacrylate-block-polymethylmethacrylate triblock(A), polymethylmethacrylate-block-polybutylacrylate diblock added triblock(B) and polybutylacrylate oligomer added triblock (C). The contact time dependency of tack measured at room temperature washigher in the order corresponding to B≒C>A and increased gradually with a contact time. The temperature dependency of tack showed the peak of tack above room temperature, and the peak ternperature was higher in the order corresponding to A>B>C. The tensile strength was higher in theorder corresponding to A>B≒C. The molecular mobility of polybutylacrylate unit measured by a 1H nuclear magnetic resonance was higher in the order corresponding to C>B>A. From the results above, it was evaluated that the relative contribution ratio of the interfacial adhesion on the tackwas larger in the order corresponding to C>B>A.
