What holds high density polyethylene together?

A. Branching of carbon chains
B. Intermolecular forces between polymer chains
C. Addition of other atoms to the plastic
D. Carbon-carbon double bonds



Answer :

Final answer:

Intermolecular forces between polymer chains are responsible for holding high density polyethylene (HDPE) together due to its low branching and strong intermolecular interactions.


Explanation:

Intermolecular forces between polymer chains hold high density polyethylene (HDPE) together. HDPE has linear molecules that pack closely together due to low branching, creating strong intermolecular forces. This results in HDPE having high tensile strength and being used in products like milk jugs and water pipes.
