Provide the mechanism for the step-growth polymerization of citric acid and ethylene glycol to form poly (ethylene glycol)-citrate. Show all steps.
Poly(ethylene terephthalate) is a linear polyester that can be synthesized from the condensation polymerization between terephthalic acid and ethylene glycol, as shown previously in Equation 26-27. What alcohol would you react with terephthalic acid to produce a branched polyester? Draw a portion of the resulting polymer that shows a main chain and one branching point.
Poly(vinyl alcohol), a hydrophilic polymer used in aqueous adhesives, is made by polymerizing vinyl acetate and then hydrolyzing the ester linkages. We have seen that basic hydrolysis destroys the Dacron polymer. Poly(vinyl acetate) is converted to poly(vinyl alcohol) by a basic hydrolysis of the ester groups. Why doesn’t the hydrolysis destroy the poly(vinyl alcohol)polymer?
