Which consequence results when sulfur molecules replace hydrocarbons?

A)Increased polymer chain flexibility improves processing
B)Oxidation stability decreases due to weakening
C)Glass transition temperatures will shift higher
D)The coefficient of thermal expansion lowers

💡 Explanation

Increased dipole-dipole interactions from C-S bonds (relative to C-H) via induced dipole-dipole leads to a higher glass transition temperature. This is because the increased intermolecular interactions resist chain movement, therefore, more thermal energy must be added, rather than chain slippage.
