摘要

Inclusion complexes (ICs) composed of α-cyclodextrins (α-CD) and biodegradable comblike copolymers with poly(α

β-malic acid) (PMA) backbones and methylated poly(ethylene glycol) (mPEG) side chains were prepared by the host-guest reaction. Two series of ICs with mPEG750 and mPEG2000 were prepared. The stoichiometry (EG/CD) of all the ICs in mPEG2000 series was 3.1

no matter what the graft degree was. While in mPEG750 series

the stoichiometry (EG/CD) was very different; it increased with the amount of mPEG decreasing. The decomposition temperatures of the fragments in ICs were closely related to graft degrees. The stack of α-CDs in ICs was a channel-type structure. The crystal of ICs was lamellar

and it could be reorganized to well-defined supermolecular structure.
