Gutta percha rubber is_________________?
Correct answer: A. An isomer of natural rubber
- A. An isomer of natural rubber
- B. Soft & tacky at room temperature
- C. A thermosetting resin
- D. Recovered by coagulation of rubber latex
Explanation
Gutta percha is the trans isomer of natural rubber, whereas ordinary natural rubber is mainly the cis form. This difference in configuration makes gutta percha harder and less elastic at room temperature.
