 (i) Following are the differences between an addition and a condensation polymer:

Addition Polymers (a) These are obtained by the addition reactions of unsaturated compounds containing double and triple bonds. For example, polythene is an addition polymer. One addition polymer is teflon also. 

Condensation Polymers
These are obtained by the condensation reactions between two different organic compounds (called monomers).(b) No simple molecule such as water is eliminated during this process. Simple molecule such as water is eliminated during this process. (c) . For example, polyester is a condensation polymer. One condensation polymer is polyester.
