Question 1:
The density and associated percent crystallinity for two polypropylene materials are as follows:
Crystallinity (%)
62.8
54.4
p (g/cm³)
0.904
0.895
(a) Compute the densities of totally crystalline and totally amorphous polypropylene.
(b) Determine the density of a specimen having 74.6% crystallinity.
(c) Determine the percent crystallinity of a specimen having a density of 1.382 g/cm³
