Chapter 26, Problem 26.17YT

Interpretation Introduction

Interpretation:

To provide the mechanism for the reaction that occurs in Equation 26-33 and to determine the second product of the reaction.

Concept introduction:

Because of the large number of hydroxyl groups off the main chain, PVA is soluble in water and is used in a large number of water-based products. Poly(vinyl acetate) can then undergo base-catalyzed transesterification to remove the acetyl groups and produce PVA. The extent of deacetylation can vary from 80% to 99.3%, depending on the desired properties of the polymer.
