PET is a polymer which is also commonly known as Dacron. It is resistant to creases and is thus used to bind with natural fibres like cotton and wool. Complete answer: Polyesters are the products of polycondensation reactions between diols and dicarboxylic acids. PET is the abbreviated form of Polyethylene terephthalate. It is formed as a result of the polymerization reaction between ethylene glycol and terephthalic acid. Thus, it is a polyester. Thus, the correct answer is B. Additional Information: Polymerization can be of two types, namely condensation polymerization and addition polymerization. In the question, we will discuss only addition polymerization: Addition polymerization is the polymerization that occurs by the simple linking between the monomer units without the formation of any by- products. In other words, it occurs through the coupling of monomers by using their double or triple bonds. An example of additional polymerization is polyethylene made from ethylene monomer units. The double bond in each ethene molecule opens and both the carbon atoms form new carbon- carbon single bonds with two other ethene molecules resulting in the formation of a polyethylene polymer. Note: Polymer is a Greek word which means many parts. Polymerization is the process of the combination of relatively small molecules to produce a long chain or a network structure. This large molecule is known as a polymer. The small units that combine and make up a polymer are known as monomers. The monomer units can either all be the same or they might be two or more different compounds.
