Definition of Polyethylene Terephthalate. "A polyethylene terephthalate is a condensation polymer of both terephthalic acid and ethylene glycol.". The reaction's by-product to create this compound is water, and so it is an example of step-growth polymerization or condensation. Based on this mechanism, there are two types of polymerization.
