“…4 Although Kato et al reported radical polymerization of 1 in the presence of benzoyl peroxide, they did not provide the detailed data such as the yield and the structure of the polymer obtained. 6 The radical homopolymerization of 1 was performed in the presence of the radical initiators for 24 h under various conditions. The results are shown in Table I.…”

Synthesis and radical polymerization behavior of N-vinylsaccharin (1) are described. Radical homopolymerization of 1 was carried out in the presence of a radical initiator for 24 h to afford the polymer containing a saccharin moiety in the side group, which was insoluble in common organic solvents. Among the copolymers of 1 with various vinyl monomers such as vinyl acetate (VAc), methyl acrylate (MA), acrylonitrile (AN), and styrene (St), only the copolymer [copoly(1-St)] obtained from 1 and St was soluble in common organic solvents. In the copolymerization of 1 and St, the Q and e values of 1 were estimated to be 0.10 and Ϫ1.60, respectively. These values are similar to those of N-vinylphthalimide (Q ϭ 0.36, e ϭ Ϫ1.52). The reaction of copoly(1-St) with LiAlH 4 was carried out in THF for 24 h to convert the saccharin moiety into the ring-opened structure bearing hydroxy and sulfonamide groups.
