概要	The mixing of an acrylate (I) bearing secondary ammonium salt moiety and terminal di-tert-butylphenyl group with dibenzo-24-crown-8 (DB24C8) afforded the pseudorotaxane monomer (II). The assocn. const. Ka was 18 L mol-1 in CDCl3 at 25 °C. An equimolar mixt. of I and DB24C8 was heated at 60 °Cin the presence of AIBN to give side-chain-type polyrotaxane. The incorporation ratio of the rotaxane unit, which is denoted by R, in the polyrotaxane was 0.42. The effect of the molar ratio [DB24C8]/[I] on the R value was complicated. The R value increased until [DB24C8]/[I] reached 1.0 in benzene, chlorobenzene, and 1,2-dichloroethane. When [DB24C8]/[I] > 1, however, the R value increased gradually as [DB24C8]/[I] increased in polar solvent such as 1,2-dichloroethane, while the R value rather decreased in less polar solvent such as benzene. The copolymn. of II and styrene afforded the corresponding copolymer.
