Chemistry - Polymer Question with Solution | TestHub
Count number of polymers which are condensation polymers as well as co-polymers :
(1) Polythene (2) Nylon-6, 6
(3) Nylon-6, 10 (4) Dacron
(5) Bakelite (6) Melamine formaldehyde resin
(7) Polyisoprene (8) Styrene-butadiene rubber (Buna-S)
(9) PAN (10) Teflon
Answer:
Solution:
The total count of polymers that are both condensation polymers and co-polymers is 5.
* These specific polymers are Nylon-6,6 (2), Nylon-6,10 (3), Dacron (4), Bakelite (5), and Melamine formaldehyde resin (6).
* They are co-polymers because they are synthesized from two different types of monomer units.
* They are condensation polymers because their polymerization involves the elimination of small molecules like water.
* The remaining listed options are either addition polymers, homopolymers, or both (e.g., Polythene, Buna-S, Teflon).
