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. 

CONDENSATION POLYMERISATION:

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:
