Polyester is a polymer consisting of ester units. When a dihydric alocohol like Ethylene
glycol reacts with a aromatic acid like Phthalic acid with two acid groups, the reaction can proceed under suitable conditions to make a polymeric ester " Polyester"
One OH group of one alcohol molecule reacts with one COOH Croup of the phthalic acid, and the remaining COOH group of the acid reacts with another OH group of another alocohl and thus reacts alternativerly alcohol and acid to form a chain of polymeric Polyester.
2 (HO.CH2.CH2.OH) + HOOC.C6H4.COOH -> HO.CH2.CH2.COO.C6H4.COO.CH2.CH2.OH + 2 H2O
iTREACTS FURTHER WITH MORE PHTHALIC ACID TO GIVE
HO. n(CH2.CH2.COO.C6H4.COO.) CH2.CH2.OH
molecular formula :]-kyrstiann dynae :]
It is a molecular species with the formula C6H12O6
The empirical formula C2H3 has a molecular mass of 27 (C: 12, H: 1). To determine the molecular formula with a molecular mass of 54, the molecular formula would simply be double the empirical formula, so the molecular formula would be C4H6.
