← ScienceWhich consequence diminishes the strength of thermoset polymers?
A)Ester hydrolysis chain scission✓
B)Increased dispersion forces network
C)Volumetric shrinkage stress relief
D)Enhanced crosslinking density stability
💡 Explanation
Ester hydrolysis weakens thermosets because chain scission breaks the covalent ester bonds linking the polymer network. This degrades the material, therefore reducing the polymer's strength, rather than increasing force dispersion, volumetric shrinkage, or crosslinking.
