Column I (Polymers) | Column II (Monomers) | ||
---|---|---|---|
(A) | Buna-N | (i) | Phthalic acid and ethtylene glycol |
(B) | Nylon-6,6 | (ii) | Terephthalic acid and ethylene glycol |
(C) | Dacron | (iii) | Hexamethylene diamine and adipic acid |
(D) | Glyptal | (iv) | Acrylonitrile and butadience |

Solution
(d): Buna-N : Polymer of CH2=CH(CN) (acrylonitrile) and H2C=CH−−CH=CH2 (butadiene).
Nylon-6,6 : Polymer of NH2−(CH2)6−NH2 (hexa- methylenediamine) and (adipic acid). Dacron (terylene): Polymer of and (terephthalic acid) (ethylene glycol). Polymer of (phthalic acid) and ethylene glycol.
