Which consequence results when molecular chains experience high shear?

A)Increased cross-linking occurs throughout sample
B)Chain scission weakens material strength
C)Crystallinity rises in amorphous phases
D)Glass transition temperature decreases uniformly

💡 Explanation

Chain scission results under high shear because mechanical stress exceeds the covalent bond energy; therefore bond breakage occurs at weakest points, rather than causing alternative cross-linking actions requiring specific chemical reactions or overall changes in material properties.
