Abstract

The IR spectra of films of PVA subjected to acetalation with furfural and to coupling with maleic anhydride by the diene synthesis have been obtained, and an assignment of absorption bands is given. The alkali treatment of the adduct of poly(vinyl furfural acetal) with maleic anhydride is apparently accompanied by the epimerization of one carboxyl group.
