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 ethylene glycol and teraphthalic acid and the polymer of 1.2 − diminoethane and teraphthalic acid.

Solution Summary: The author identifies the rigid or stronger polymer from the given pair of polymers. The amine group forms hydrogen bond with the carbonyl carbon within the molecule.
Definition Definition Large and very high-molecular-weight substances that consist of hundreds to thousands of repeating units. Polymers are also known as macromolecules. Number-average-molecular weight is the measuring system for the polymers.
