J. Watanabe et al., PREPARATION AND CHARACTERIZATION OF A POLYROTAXANE WITH NONENZYMATICALLY HYDROLYZABLE STOPPERS, Chemistry Letters, (10), 1998, pp. 1031-1032
A degradable polyrotaxane, in which many alpha-cyclodextrins are threa
ded onto the poly (ethylene glycol) capped with L-phenylalanine via es
ter linkages, was synthesized and characterized for use as new implant
able materials.
