← ScienceWhich consequence results from increasing ionic character in polymer chains?
A)Reduced chain mobility✓
B)Enhanced solvent solubility
C)Decreased thermal stability
D)Lower glass transition temperature
💡 Explanation
Increasing ionic character between polymer chains causes increased electrostatic attraction via ionic bonding, restricting chain flexibility. Greater restrictions result in reduced chain mobility because stronger intermolecular forces dominate, therefore it increases the materials stiffness rather than enhancing solubility.
