← ScienceWhich outcome occurs when misaligned polymerization creates branched polymer chains?
A)Reduced polymer crystallinity occurs✓
B)Increased tensile strength results
C)Higher glass transition temperature
D)Solvent resistance improves greatly
💡 Explanation
Bent geometry inhibits ordering; branching interferes with efficient packing during crystallization; *steric hindrance* arises because these substituent groups repel, therefore the material has low crystallinity. This weakens it, rather than increasing strength as the alternative may do.
