← ScienceWhich consequence results when a polymer's side chains hinder chain folding?
A)Increased glass transition temperature✓
B)Decreased elastic modulus result
C)Enhanced chain entanglement appear
D)Increased crystalline domain sizes
💡 Explanation
Increased hindrance increases the glass transition temperature because hindered chains require greater thermal energy to overcome the forces and induce chain mobility and segmental relaxation by steric hindrance, therefore increased temperature is required rather than the opposite.
