Options:
A) Without proper control, atactic polypropylene is produced
B) During polymerization, a secondary free radical is produced in every step
C) Use of Ziegler-Natta catalyst results in isotactic polypropylene
D) During polymerization, a linear, unbranched, crystalline polymer is usually obtained
