Solution

Condensation polymerization:-

  1. Condensation polymerization is a type of polymerization reaction in which two monomer molecules of same or different types having at least two functional groups are joined together to form a large polymeric chain.
  2. Small molecules like water, and alcohol, are obtained as the byproducts in this reaction.

Preparation of Terylene:-

  1. By the condensation polymerization of Ethylene glycol and p-terephthalic acid (1,4-benzene dicarboxylic acid), Terylene is obtained.
  2. This reaction is done under the presence of a weak base like Calcium acetate.
  3. The two monomers of Ethylene glycol and p-terephthalic acid (1,4-benzene dicarboxylic acid) are condensed and then after the removal of water, we obtain Terylene or dacron.
  4. This reaction takes place under a temperature between 500K.
  5. Here a mixture of Zinc acetate and Antimony trioxide is used as a catalyst.

Therefore, Terylene is formed by condensation polymerization of Ethylene glycol and p-terephthalic acid (1,4-benzene dicarboxylic acid).
