← ScienceWhich consequence results when epoxy polymer chains degrade?
A)Decreased cohesive strength of bonding✓
B)Increased thermal expansion coefficient
C)Improved resistance to chemical solvents
D)Enhanced electrical insulation properties
💡 Explanation
Decreased cohesive strength reduces load bearing because hydrolysis severs polymer bonds; therefore the material weakens, rather than becoming more flexible or chemically resistant under greater strain.
