Acrylamide can be graft copolymerized onto poly(vinyl alcohol) in aqueous solution with initiation by cerium(IV) under acid conditions in order to produce an appropriately functionalized polymer directly or by subsequent chemical modification. Initiation proceeds through the decomposition of a complex between the PVA1 and Ce(IV) and under normal conditions occurs only through the 1, 2‐glycol units in the PVA1. Illumination by light in the absorption wavelength range of the complex accelerates the rate of graft copolymerization. Moreover, initiation now proceeds through the 1,3‐glycol units.
