Question

From the practical standpoint, is it better to use a "good" solvent or a "poor" solvent when measuring polymer molecular weight? Explain.

Expert Solution
Step 1

Polymer molecular weight is an important characteristic that influences various properties such as viscosity, mechanical strength, and thermal stability. The measurement of polymer molecular weight can be accomplished through a variety of techniques, each with its own advantages and disadvantages. The choice of solvent is a critical factor in the measurement of polymer molecular weight and can greatly affect the accuracy and reliability of the results. In this answer, we will discuss the importance of choosing the appropriate solvent for measuring polymer molecular weight, and the difference between "good" and "poor" solvents
