Define a polymer. Write the monomer used for the preparation of dacron. Mention a use of it.
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.
Write the names and structures of the monomers of the following polymers:
(i) Polystyrene (ii) Neoprene.
Write the names and molecular structure of the monomers of the following:
(i) Natural rubber (ii) Neoprene.
Give the monomers and uses of each of the following addition polymers:
(a) Polyethylene
(b) Polypropylene
(c) Polystyrene.
What are linear polymer and branched chain polymers? How do these differ from own linked polymers?
