← ScienceDuring the production of polyethylene films which consequence results when branching increases?
A)Reduced van der Waals forces✓
B)Enhanced degree of polymerization
C)Increased glass transition temperature
D)Elevated resistance to tear propagation
💡 Explanation
Increased branching disrupts chain packing, reducing intermolecular distances. Because branching introduces steric hindrance, London Dispersion forces weaken, therefore lowering tensile strength rather than increasing polymerization or improving tear resistance at the micro level.
