Poly(vinyl alcohol), a hydrophilic polymer used in aqueous adhesives, is made by polymerizing vinyl acetate and then hydrolyzing the ester linkages. Vinyl acetate is an ester. Is poly(vinyl acetate) therefore a polyester? Explain.
Poly(vinyl alcohol), a hydrophilic polymer used in aqueous adhesives, is made by polymerizing vinyl acetate and then hydrolyzing the ester linkages. Why is poly(vinyl alcohol) made by this circuitous route? Why not just polymerize vinyl alcohol?
