Solution
Addition polymerization
In additionpolymerization, the molecules of the same or different monomers simply add on to one another leading to the formation of a macromolecules without elimination of small molecules like H2O, NH3 etc. Addition polymerization generally occurs among molecules containing double and triple bonds.
For example, formation of polythene from ethene and neoprene from chloroprene, etc.
Condensation polymerization
In condensation polymerization, two or more bifunctional trifunctional molecules undergo a series of independent condensation reactions usually with the elimination of simple molecules like water, alcohol, ammonia, carbon dioxide and hydrogen chloride to form a macromolecule.
For example, nylon 6,6 is a condensation polymer of hexamethylenediamine and adipic acid formed by elimination of water molecules
