Polymers
Give the monomers and uses of each of the following addition polymers:
(a) Polyethylene
(b) Polypropylene
(c) Polystyrene.
(a) Polyethylene monomer is ethylene. It is a whitish, translucent polymer of moderate strength. It is used for making containers and bottle moulds articles and as an electrical insulator.
(b) Polypropylene monomer is propylene. It is harder and stronger than polyethylene and is used as liners for bags, packing of textiles and foods.
(c) Polystyrene monomer is styrene. It is transparent polymer used for hot drink cups, toys and household articles.
