(a)
Interpretation: The rigid or stronger
Concept introduction: The hydrogen bonding, the resonance effect, and the shorter bond length increase the stability of the polymer and hence the polymer becomes more rigid.
To determine: The rigid or stronger polymer from the polymer of ethylene glycol and teraphthalic acid and the polymer of

Interpretation: The rigid or stronger polymer from the given pair of the polymer is to be identified.
Concept introduction: The hydrogen bonding, the resonance effect, and the shorter bond length increase the stability of the polymer and hence the polymer becomes more rigid.
To determine: The rigid or stronger polymer from the polymer of
(c)
Interpretation: The rigid or stronger polymer from the given pair of the polymer is to be identified.
Concept introduction: The hydrogen bonding, the resonance effect, and the shorter bond length increase the stability of the polymer and hence the polymer becomes more rigid.
