Nylon-6 as compared to nylon-66 is_________________?
Correct answer: D. None of these
- A. Harder
- B. More abrasion resistant
- C. Having higher melting point
- D. None of these
Explanation
Nylon-66 generally has the higher melting point and slightly greater hardness and abrasion resistance than nylon-6, so none of the listed descriptions correctly characterises nylon-6 as compared with nylon-66. The answer depends on recognising that the comparison is in the reverse direction.
