Notes:
A study of the Ce(IV) ion consumption during graft polymerization of butyl acrylate with amylose was carried out. The Ce(IV) consumed was ca. 80% and the ratio of Ce(IV) to anhydroglucose units was 1/15. Poly(butyl acrylate) (PBA) chains were isolated from the grafted copolymer by the perchloric acid hydrolysis method. The molecular distribution was obtained by gel permeation chromatography (GPC). The number-average molecular weight (Mn) of the grafted chains was 276,000 and the weight-average molecular weight (Mw) was 1,320,000. The total number of grafted chains (mmol) ranged from 0.4410-3 to 8.710-3 (amylose from 0.08 g to 1.23 g). Frequency of grafting ranged from 1042 to 704.
