The physical state in which polymers exist is___________________?
Correct answer: D. All A., B. and C.
- A. Melts & rubber like state
- B. Amorphous glassy state
- C. Partially crystalline state
- D. All A., B. and C.
Explanation
Depending on chain structure, temperature and processing, polymers may occur as melts or rubber-like materials, amorphous glassy solids, or partially crystalline solids. Thus all three listed physical forms are possible.
