Question
The density of a polyethylene (PE) crystal (20 C) is = 1.014 g cm-3. The density of amorphous PE (20C) is = 0.84 g cm-3.
The density of a polyethylene (PE) crystal (20 C) is = 1.014 g cm-3. The density of amorphous PE (20C) is = 0.84 g cm-3.
Please calculate the degree of crystallinity (%) in:
a) Low-density PE (LDPE) with LDPE = 0.92 g cm-3 (20C).
b) High-density PE (HDPE) with HDPE = 0.97 g cm-3 (20C).
