Explanation:
An addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products.
Glucose is the monomer of polysaccharides like starch, cellulose. Image result for polyethylene formation reaction
Polyethylene \((PE)\) is made by the reaction of multiple ethylene molecules in the presence of a catalyst to break the double bond and connect the carbon atoms into a chain without forming any by-products.
Ethylene is the monomer of polyethylene.
Terylene is a synthetic polyester fiber produced by polymerizing ethylene glycol and terephthalic acid which is obtained from petroleum with the removal of water. Hence, a condensation polymer. (Condensation polymers are formed through a condensation reaction, where molecules join together and lose small molecules as by-products such as water or methanol.)Polythene is an addition polymer.
