CHEMICAL STRUCTURE AND FORMULA OF POLYESTER FIBRE
CHEMICAL STRUCTURE OF POLYESTER FIBRR, CHEMICAL FORMULA OF POLYESTER FIBRE
SYNTHESISATION OF POLYMER:
The polyethylene teraphthalate is used as a condensation polymer. The polyester polymer is commersially produced by condensation polymerization of ethylene glycol with either dimethyl terephthalate or terephthalic acid. -
1- Terephthalic acid.
2 - Dimethyl terephthate.
3 - Ethylene glycol.
PRODUCTION OF POLYETHYLENE TEREPHTHELATE BY USING PTA:
In condensation polymerisation, during the joining of monomers together a small molecule is eliminated. “A polyester is made by a reaction involving an acid with two -COOH groups, and an alcohol with two -OH groups”. The reaction follows below chemical equation:
