Q8E
Question
Poly(ethylene terephthalate), or PET, is a polyester used to make soft-drink bottles. It is prepared by reaction of ethylene glycol with 1,4-benzenedicarboxylic acid (terephthalic acid). Draw the structure of PET.
Step-by-Step Solution
Verified Answer
The structure of PET followed as:
1Step 1: PET
PET stands for polyethylene terephthalate it is a macromolecule formed by the polymerization of the number of monomeric units and it’s formed by two different monomers that are terephthalic acid and ethylene glycol followed by the esterification.
2Step 2: PET formation
PET also called pure terephthalic acid (PTA) is formed by the polycondensation of the ethylene glycol and terephthalic acid. The polymerization is occurred at low
temperatures as followed:
