Chapter 26, Problem 26.61P

Interpretation Introduction

Interpretation:

Which polymer in Problem $\text{26}\text{.34 }\left(\text{p}\text{. 1363}\right)$ is the most soluble in ethanol is to be determined.

Concept introduction:

When intermolecular interactions involving solvent molecules are similar to those involving polymer molecules, the polymer tends to dissolve. Non polar aromatic polymers dissolve in non-polar aromatic solvents. A polymer with $\text{OH}$ group dissolves in water because its hydroxyl groups can form hydrogen bond with water. Polymers with ionic side groups dissolve even more readily in water due to ion-dipole interactions. Any factors that limit the interactions between the solvent molecules and the polymer will decrease solubility.
