Not in JEE Main or NEET syllabus
Which from following polymers needs HO-CH_2-CH_2-OH as one of the monomers for its preparations?
Answer: (B)
Solution
Ethylene glycol (HO-CH_2-CH_2-OH) undergoes condensation polymerisation with terephthalic acid (or dimethyl terephthalate) with loss of water/methanol to give polyethylene terephthalate, i.e. Dacron (Terylene). Hence option (B).
