Question 2
In step-growth polymerization, how does the molecular weight of the polymer change with reaction conversion?
Question 3
Which of the following best explains why amorphous polymers typically exhibit a glass transition temperature ($T_g$) but not a distinct melting temperature ($T_m$)?
Question 4
What is the primary effect of cross-linking on the solubility of a polymer?
Question 5
Consider a highly branched polymer. How would its melt viscosity typically compare to a linear polymer of the same molecular weight?
