| Outline of Final Research Achievements |
An initial adhesion process of tacky adherent polymers, i.e., pressure sensitive adhesive (PSA)s was investigated to examine the correlation between dynamic wettabilities and dynamic mechanical properties for acrylate series PSAs. We found that the orientational mobilities of molecules and segments on the sample surface, occurred as a result of dynamic wettabilities of acrylate series PSAs depended on the alkyl chain lengths and the membrane thicknesses. In addition, it was revealed that the short-aged adhesion strengths of these PSAs were deeply correlated with “a development in wetting on the interface”, in particular, some sliding properties (dynamic contact angles) of liquid droplets on the sample surface.
