Which property change occurs when high molecular weight polyethylene is stretched?

A)Increased crystallinity and tensile strength
B)Decreased crystallinity and tensile strength
C)Reduced chain alignment prevails
D)Amorphous regions become cross-linked

💡 Explanation

Stretching polyethylene causes strain-induced crystallization via chain alignment. This orientation increases intermolecular forces, resulting in higher crystallinity and strength. Therefore, tensile strength increases, rather than decreases, because chain alignment occurs promoting crystallization.
