Bond strengths are closely associated with the dynamic mechanical properties of adhesive polymers,especially, they have their maximum around glass transition temperatures(Tg)of adhesive polymers.Here power feed copolymers, which had broad Tg, were synthesized, characterized, and applied aswood adhesives. Surface and interphase are very important for adhesion, especially for PSAs as wellas dynamic mechanical properties. Here, rheological properties of surface was measured as nano frictionalforce by AFM, of which method is considered to be a new evaluation of surface physical propertiesincluding nano surface fracture modes.
