what is source of polyester
Answers
Answer:
Petroleum
Explanation:
Synthetic polyester is made using a chemical reaction involving coal, petroleum, air and water.
This material is made up of purified terephthalic acid (PTS) or its dimethyl ester dimethyl terephthalate (DMT) and monotheluene glycol (MEG).

Answer:
Polyester was developed in the years 1939-1941 by British chemists at Calico Printers Association, Ltd., based on the work of W.H. Carothers in 1926 at the United States based E.I.D. Pont de Nemours and Co. DuPont bought the rights in 1946 to produce polyester fiber in the United States. By 1951, DuPont had begun to market the fiber under the name Dacron....MEANING
Polyester is made up of long-chain polymers. Today there are two primary types of polyester called polyethylene terephthalate (PET) and poly-1, 4-cyclohexylene-dimethylene (PCDT). PET is the most popular type as it is applicable to a wider variety of uses and is stronger than PCDT. However, PCDT is more elastic and resilient and is used in heavier consumer applications.
Synthetic polyester is made using a chemical reaction involving coal, petroleum, air and water. This material is made up of purified terephthalic acid (PTS) or its dimethyl ester dimethyl terephthalate (DMT) and monotheluene glycol (MEG). It holds 10% of the market share for all plastic materials, coming third in terms of popularity after polyethylene (33.5%) and polypropylene (19.5%).

The most common type of chemical reaction used to make polyester takes place at high temperatures in a vacuum. A petroleum by-product, alcohol, and carboxyl acid are mixed to form a compound known as monomer or “ester.” This reaction is known as polymerization. The polymer material created during polymerization is extruded while hot into long fibers that are stretched until they are about five times their original length. The resultant fiber forms an arrangement of molecules that is very
