Question
Define a polymer. Write the monomer used for the preparation of dacron. Mention a use of it.
Solution
A polymer is large but single chain-like molecule in which the repeating units derived from small molecules called monomers, are covalently linked. The process by which monomers are transformed into a polymer is called polymerization.
The monomers used for dacron is ethylene glycol (ethane-1,2-diol) and terephthalic acid (1,4-benzene dicarboxylic acid).
It gives a strong fibre hence used to blend cotton in clothing.
