摘要：

Amphiphilic copolymers containing beta-cyclodextrin (beta-CD) core were synthesized successfully. Synthesis was initiated from tosylated cyclodextrin ((Tosyl)(7)-beta-CD) which is containing two types of functional groups. Hydroxyl functional groups of (Tosyl)(7)-beta-CD were used as initiator for ring opening polymerization of lactide. This step led to star polymers containing tosylated cyclodextrin core and polylactide arms (PLA-(Tosyl)(7)-beta-CD). In the next step, tosyl groups of PLA-(Tosyl)(7)-beta-CD were used as initiator for ring opening polymerization of 2-ethyl-2-oxazoline and amphiphilic copolymers containing cyclodextrin core, PLA and poly(2-ethyl-2-oxazoline) arms (PLA-beta-CD-POX) were obtained. Loading of Congo red as guest molecule by amphiphilic copolymers was investigated. The release of guest molecule from chloroform solution of copolymers to water phase was also investigated.
