This was quite a curve-fitting challenge that
would not have been possible without the
help of a curve-fitting program like the
Excel Solver. The Solver search results,
shown in Figure 14, indicate that the film
was made up by three resin components -
iPP, mLLD, and a ZN-LLD - with the
estimated weight percentage of 10, 40, and
50%, respectively. The co-added curve
from this three-resin combination for each
detector is shown in Figure 14 and com-
pared with the 3D-TREF data of
