Abstract : The project as finally funded was cast in the form of a proof-of-concept study with a narrow focus. The objective was to demonstrate the feasibility of characterizing tackifier concentration depth profiles in pressure sensitive adhesive films and correlating these profiles with adhesive performance. Thin films of isoprene and mixed with various amounts of an abietic acid ester tackifier were studied using a combination of neutron reflectometry (NR), forward recoil spectroscopy (FRES), x-ray reflectometry (XR) and ellipsometry (EL) to provide unprecedented spatial resolution of the near surface profile.
