- P-4; Q-3; R-2; S-1
- P-4; Q-2; R-3; S-1
- P-2; Q-1; R-4; S-3
- P-2; Q-1; R-3; S-4
The Correct Option is A
Solution and Explanation
- Polyurethane (P) is synthesized from the reaction of hexamethylene diisocyanate and tetramethylene glycol, making the correct monomer combination (4).
- Epoxy (Q) is synthesized from pyromellitic anhydride and p,p'-diaminodiphenyl ether, which is a typical method for producing epoxy resins, corresponding to (3).
- Polyimide (R) is synthesized from epichlorohydrin and bisphenol A, which forms the imide linkage required for polyimide synthesis, making it (2).
- Polyester (S) is commonly made from maleic acid and propylene glycol, which is a typical monomer combination used in the synthesis of polyester resins, corresponding to (1).
Thus, the correct matching is (A) P-4; Q-3; R-2; S-1.
Top Questions on Polymer Science
The crystallization of a polymer can only proceed in a temperature range limited to glass transition temperature (\(T_g\)) on the lower side, and the equilibrium melting point (\(T_m^0\)) on the higher side. Around \(T_g\), the mobility of the polymer chains is lower, while in the proximity of \(T_m^0\), crystal nucleation is inhibited.
