Monomers of Dacron polymer is
AEthylene glycol and terephthalic acid
BEthylene oxide and phthalic acid
CEthylene glycol and benzoic acid
DBenzamide and terephthalic acid
Answer:
A. Ethylene glycol and terephthalic acid
Read Explanation:
Dacron (Polyethylene Terephthalate - PET)
- Monomers: The condensation polymerization of Ethylene Glycol (ethane-1,2-diol) and Terephthalic Acid (benzene-1,4-dicarboxylic acid) produces Dacron.
- Chemical Class: It is classified as a Polyester because the monomer units are linked by ester functional groups formed through the elimination of water molecules.
- Mechanism: The reaction occurs via step-growth polymerization, typically performed at high temperatures (around 420-460 K) in the presence of zinc acetate-antimony trioxide catalysts.
- Properties:
- Dacron is highly resistant to chemical degradation and moisture.
- It exhibits high tensile strength and durability.
- It is widely used in the textile industry for manufacturing synthetic fibers and in packaging materials like plastic bottles.
- Alternative Name: In the context of industrial fibers, it is commonly referred to as Terylene or PET (Polyethylene Terephthalate).
