monomers The small molecules from which a polymer is made.

Linear polymer They are in the form of long chains. Generally they consist of carbon atoms which are held together by covalent bonding, with other atoms or groups which are attached to the carbon atom.
elastomers These are also called cross linked polymers,they are like ladders, they form in long chains and they are connected every now and then with a smaller chain of atoms, they made of elastic
Cross linked polymers They are largely made up of carbon atoms, they are giant covalent lattices.
Thermoplastic Polymers softens when heated gently and solidify again when cooled. they are readily worked into different shapes.
Thermosetting polymer do not melt or change shape when heated. If heated very strongly they might turn black, These must produce in mould because they can only be formed once. (eg. playstation 3_
