Which outcome occurs when molecular chain branching increases in polyethylene?

A)Ultimate tensile strength decreases
B)Crystallinity of polymer structure increases
C)Polymer density exhibits an increase
D)The glass transition temperature declines

💡 Explanation

Increased branching interferes with chain packing because the Van der Waals forces are disrupted; this decreases tensile strength. Therefore, tensile strength decreases rather than crystallinity affecting density because of the molecular chain conformations.
