Synthetic Polymer

WHAT ARE POLYMER

1.Molecule that consist of a large number of small identical or similar units joinedtogether repeatedly are called polymer.

2.The smaller molecules that make up the repeating unit in polymer are caller monomer.

3.The process of joining together a large number of monomers to form a long chain polymer is called polymerisation.

4.Polymer can be naturally occurring or man-made (synthetic). Natural polymer are foundin plant and in animals for example of natural polymers are starch cellulose, protein andrubber.

5.Two type of polymerisation in producing synthetic polymer are additional polymerisation.6.Double bonds between two carbon atoms usually undergo addition polymerisation

Uses of synthetic polymer
SYNTHETIC POLYMER IN DAILY LIFE

1.Synthetic polymers have many advantages over other type of materials:

a.They are cheap, light-weight and translucent. 

b.They are easily coloured, easily moulded and shaped.

c.They are non-corrosive, waterproof and good insulator.d.They are durable and long lasting because they are resistant to decay, rusting andchemical attacks.

2.There are disadvantage using synthetic polymer:

a.Most of the synthetic polymer are flammable. When a synthetic polymer materialcatches fire, poisonous fumes are produce causing air pollution. 

b.Synthetic polymers are non-biodegradable. When there are discharge, they causelitter problem and pollute the environment.

c.Plastic container that are left aside in an open area collect rainwater which becomes the breeding ground for mosquitoes.

d.There are limitation in recycle have to be separated out as the addition of non-recyclable polymers in the mixture affect the properties of the recycled polymers.
