Explain with suitable examples:
(i) Natural polymers
(ii) Synthetic polymers.
(i) Natural polymers: Polymers found in nature, mostly from plants and animals, are called natural polymers. Examples are starch, cellulose, proteins, nucleic acids and natural rubber.
(ii) Synthetic polymers: Polymers synthesised by human in laboratory or factory are called synthetic polymers. Examples are polypropylene, nylon-66, polybutadiene, polyvinyl chloride (PVC), phenol formaldehyde (Bakelite), polyester (Terylene).
Write the names and structures of the monomers of the following polymers:
(i) Polystyrene (ii) Neoprene.
Define a polymer. Write the monomer used for the preparation of dacron. Mention a use of it.
Give the monomers and uses of each of the following addition polymers:
(a) Polyethylene
(b) Polypropylene
(c) Polystyrene.
Write the names and molecular structure of the monomers of the following:
(i) Natural rubber (ii) Neoprene.
What are linear polymer and branched chain polymers? How do these differ from own linked polymers?
