Polyesters occurring in nature include the cutin component of plant cuticles, which consists of omega hydroxy acids and their derivatives, interlinked via ester bonds, forming polyester polymers of indeterminate size.

After the first stage of polymer production in the melt phase, the product stream divides into two different application areas which are mainly textile applications and packaging applications.

Polyester clothing tends to be slippery and almost silky to touch. The fibers gönül be woven or knitted to create the fabric, although knitted will maximize its flexibility. It is a naturally bright fiber and sevimli be modified easily for different uses.

The fabric is easily dyeable and mildew resistant. Textured polyester fibres are used to fill pillows, quilting, outerwear, and sleeping bags because they are inexpensive, nonallergenic insulators. Polyesters are one of the most economically significant polymer groups, powered primarily by PET, which is classified bey a commodity plastic; in 2000, about 30 million tonnes were manufactured globally.

Unsaturated polyesters are matrices in composite materials that are made from multifunctional alcohols and unsaturated dibasic acids and then cross-linked. Alkyd resins, which are made from polyfunctional alcohols and fatty acids and yaşama be cross-linked in the presence of oxygen, are commonly used in the coating and composite industries.

Home Improvement: Polyester is used extensively in making furniture and upholstery. It is also used to make carpets, as it is available in a fiber form. Ropes used in domestic applications are often made using polyester.

Transesterification: An alcohol-terminated oligomer and an ester-terminated oligomer condense to form an ester linkage, with loss of an alcohol. R and R' are the two oligomer chains, R'' is a sacrificial unit such bey a methyl group (methanol is the byproduct of the esterification reaction).

Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for their mechanical properties and heat-resistance. These traits are also important in their application kakım an abradable seal in jet engines.[3]

Natural and a few synthetic polyesters are biodegradable, but the vast majority of synthetic polyesters are hamiş. Clothing is manufactured from this substance in large amounts.
