Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics … See more Polyesters are one of the most economically important classes of polymers, driven especially by PET, which is counted among the commodity plastics; in 2000 around 30 million tons were produced … See more Basics Polyethylene terephthalate, the polyester with the greatest market share, is a synthetic polymer made of purified terephthalic acid (PTA) or its dimethyl ester dimethyl terephthalate (DMT) and monoethylene glycol (MEG). … See more In 1926, United States–based DuPont began research on large molecules and synthetic fibers. This early research, headed by See more Recycling of polymers has become very important as the production and use of plastic is continuously rising.
