Chemistry - Polymers Question with Solution | TestHub

PVA is prepared by hydrolysis of polyvinyl acetate. Other vinyl ester-derived polymers are sometimes used, with formate, chloroacetate groups instead of acetate. The conversion of the polyesters is usually conducted by base-catalysed transesterification with ethanol:
${\left[\mathrm{C}{\mathrm{H}}_2\mathrm{C}\mathrm{H}\left(\mathrm{O}\mathrm{A}\mathrm{c}\right)\right]}_{\mathrm{n}}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{O}\mathrm{H}\to {\left[\mathrm{C}{\mathrm{H}}_2\mathrm{C}\mathrm{H}\left(\mathrm{O}\mathrm{H}\right)\right]}_{\mathrm{n}}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{O}\mathrm{A}\mathrm{c}$
