← ScienceWhich outcome arises when applying localized heat molecularly to amorphous polymer under stress?
A)Increased chain alignment, crystallization✓
B)Reduced material density, foaming
C)Decreased impact strength, embrittlement
D)Initiated depolymerization, chain scission
💡 Explanation
Applying localized heat causes increased chain alignment and crystallization due to the mechanism of thermal chain mobility. Therefore, increased alignment occurs rather than foaming because of the controlled heating, differing from bulk decomposition.
