Poly(p-dioxanone) (PPDO) can form pseudo-polyrotaxanes (PPRs) with cyclodextrin (CD).
The formation of CD-PPRs was demonstrated using WAXD, 2DNMR, POM and FTIR analyses.
Both thermal stability and hydrophilicity of PPDO were improved via CD imprisoning.
The degradation behavior of PPDO can be controlled by the types and amounts of CDs.
