Hint: Terylene is a copolymer produced by two different monomeric units. Terylene is formed by the condensation polymerization reaction in a step-growth manner. The monomeric units of Terylene are ethylene glycol and terephthalic acid.
Complete step by step answer:
- In the question, it is asked to find the structure of the polymer terylene among the given options.
- To know the structure of the Terylene polymer we should know the structures of the monomeric units of Terylene.
- The structures of the ethylene glycol and terephthalic acid are as follows.
- The condensation polymerization of the ethylene glycol and terephthalic are as follows.
- In the above chemical reaction ethylene glycol undergoes a condensation reaction with terephthalic acid and forms terylene as the product.
- The structure of the Terylene is as follows.
So, the correct answer is “Option B”.
Additional Information”.
- The other name of Terylene is Dacron.
- Dacron is a copolymer due to the presence of two different monomeric units in its structure.
- Dacron is a linear polymer.
- Dacron has high tensile strength and consists of high resistance to stretching.
- The other chemical name of Terylene is polyethylene terephthalate and in short, the form is going to be represented as PET.
Note: In condensation polymerization there is the liberation of side products like water-methanol, water, etc. In the case of condensation polymerization of ethylene glycol and terephthalic acid, the byproduct is water.
