Polyester is a category of polymers which contain the ester functional group in their main chain.
However! the term "polyester" as a specific material most commonly refers to polyethylene terephthalate (PET), which can be made in two ways, and both are done in chambers that feature strong vacuums and high temperatures. # The first requires dimethyl terephthalate and ethylene glycol. You make it this way, and the process will liberate methanol--which you have to capture, store and figure out something to do with. (In most cases, the "something to do with it" is to mix it with terephthalic acid and feed it back into the process.) # The other is to use terephthalic acid and ethylene glycol. This requires more heat, but it produces no methanol--a very important thing when you consider how dangerous methanol is. No one wants it around if they're not using it.
Some polyesters also include naturally-occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics such as polycarbonate and polybutyrate.

∙ 9y agoIt's a type of polymer that can be made from both natural and man-made sources. It's typically used to make a fabric that is used in clothing, home items, belts, yarn, rope, bottles, tarps, canoes, finishing for wood, and many other uses.

What are synthetic fibers that consist of chains containing many esters?
polyesters
What are containers of uranium?
This depends on the quantity, chemical form, physical form, enrichment. In laboratory, for small samples, can by used bottles from glass, polyethylene, polypropylene, teflon. In industry containers of stainless steel or polyesters reinforced with glass fibers can be used. For uranium fluorides nickel alloys are recommended.
Reactivity and synthetic applications of malonic ester?
Esters are widespread in nature and are widely used in industry. In nature, fats are, in general, triesters derived from glycerol and fatty acids.[5] Esters are responsible for the aroma of many fruits, including apples, pears, bananas, pineapples, and strawberries.[6] Several billion kilograms of polyesters are produced industrially annually, important products being polyethylene terephthalate, acrylate esters, and cellulose acetate.[7]
Give examples for esters?
ATP - adininetriphosphate is an orgainic ester as far as i know...its on inorganic ester because it cantains phosphorus
What are examples of a natural polymer?
cellulose Starch (amylose and amylopectin) proteins silk, spider webs are also poly-peptides (proteins) and are natural polymers polyhydroxyalkanoates (natural polyesters made by bacteria as food reserves) deoxyribonucleic acid (DNA) Natural Rubber Many polysacharides: Xanthan gum, B-Glucans, chitosan (from crab, shrimp, lobster shells) Enkephaline
Is polyesters thermoplastic?
Polyesters are a group of organic polymers that contain the ester functional group in their main chain. Polyesters can be either thermoplastic or thermoset, depending on the rest of their structure, but the most common polyesters are thermoplastic.

What is polyester used to make?
Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polycarbonate and polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not.Depending on the chemical structure, polyester can be a thermoplastic or thermoset; however, the most common polyesters are thermoplastics.

Is polyster sustainable?
Did you mean POLYESTER, I suppose.It depends of the way it is made, of the production methods used by the factory.So there are sustainable polyester tissues and other non sustainable.From Wikipedia we get:Polyester is a category of polymers which contain the ester functional group in their main chain.
