摘要

<正>Both four-arm star-shaped poly（ε-caprolactone）（4sPCL） and two-arm linear PCL （2LPCL） were synthesized and their inclusion complexation withα-cyclodextrin （α-CD） were studied. The inclusion complexes （ICs） formed between the PCL polymers andα-CD were characterized by 1H-NMR

DSC

TGA

WAXD

and FT-IR

respectively. Both branch arm number and molecular weight of the PCL polymers have apparent effect on the stoichiometry （CL:CD

mol:mol） of these ICs. All these analytical results indicate that the branch arms of the PCL polymers are incorporated into the hydrophobicα-CD cavities and their original crystalline properties are completely suppressed. Moreover

the inclusion complexation between two-arm linear or four-arm star-shaped PCL polymers andα-CD not only enhances the thermal stability of the guest PCL polymers but also improves that ofα-CD.
