← ScienceWhich behavior dominates as molecular chain branching increases?
A)Tensile strength dramatically decreases
B)Intermolecular entanglement becomes enhanced
C)Recrystallization rates substantially increase
D)Polymer density often reduces rapidly✓
💡 Explanation
Increased branching causes lower density because branching inhibits efficient chain packing, therefore density decrease dominates, rather than changes in either entanglement due to topological constraints or properties related directly to chain deformation like strength.
