Molecular weights of plastics ranges from_______________?
Correct answer: B. 20000 to 25000
- A. 1000 to 5000
- B. 20000 to 25000
- C. 5000 to 1000
- D. 109 to 1011
Explanation
The molecular weight of many commercial plastics is commonly quoted in the range of about 20,000 to 25,000 in introductory polymer texts. The other ranges are either incorrectly ordered or far outside the usual stated range for this question.
