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.
The compound is 4-ethoxy-1,3-benzenedicarboxylic acid, also known as dimethyl terephthalate. It is a chemical used in the production of polyesters and plastics.
Polyester fibers consist of chains containing many esters. Polyester is a type of synthetic fiber that is known for its durability, wrinkle resistance, and ability to retain its shape and color well. It is commonly used in clothing, furnishings, and other textiles.
There are a few and they are similar to those used in paints and coatings. they include, nitrocellulose, PVA, acrylics, styrene - acrylics, epoxy and alkyds. Also increasingly used are UV and electron beam cured.
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.
Some common examples of esters include ethyl acetate (smells like nail polish remover), methyl salicylate (smells like wintergreen), and isoamyl acetate (smells like bananas). Esters are commonly used as fragrances and flavorings in perfumes, cosmetics, and food products.
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 the main difference between polyethylene and polyesters what is the main difference between polyethylene and polyesters
Polyesters are primarily made from petrochemical sources, specifically derived from fossil fuels like crude oil. The most common type of polyester, polyethylene terephthalate (PET), is produced through a reaction between ethylene glycol and terephthalic acid, both of which are synthesized from petroleum. Additionally, bio-based polyesters can be produced from renewable resources, such as plant-derived sugars, but traditional polyesters heavily rely on chemical processes involving fossil fuels.
Answer Some polyesters contain the mineral antimony.
Polyesters contain carbon, hydrogen and oxygen.

Polyesters contain C, H, O.

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.

The catalyst commonly used in making polyesters is an esterification catalyst, such as an acid catalyst like sulfuric acid or an organic acid like p-toluenesulfonic acid. These catalysts help facilitate the reaction between the diol and the dicarboxylic acid to form the polyester polymer.
