Table below lists absorption values of an FT-IR band at 1530 cm^-1 due to bending vibrations of polyethylene in polyethylene/polybutadiene (PE/PBT) blends.

Absorbance PE/PBTmol. ratio
0.2 0.10
0.4 0.25
0.6 0.40
0.8 0.55

A. Using the above data determine the extinction coefficient for the 1530 cm^-1 band in PE.

B. Determine the molar ratio of PE in PE/poly(methylmethacrylate)(PE/PMMA) blend for which the measured absorbance value of the 1530 cm^-1 band was 0.54
