Poster summary

In this study, highly stretchable low covered movable slide-ring polymer flim was synthesized by crosslinking poly(propylene glycol)-methyl-β-cyclodextrin polyrotaxane(MePR) with diisocyanate. Methylated polyrotaxane was synthesized from methylated β-cyclodextrin (Me-β-CD) and poly(propylene glycol) (PPG) with a molecular weight of 4000, and expected to have higher elongation properties than full covered polyrotaxane because of easier movement of ring structure along the main chain. The slide ring movement of crosslinked Me-β-CD on polyurethane backbone allows to stretch without deformation. These unique properties of the resulting polyurethane potentially act as flexible materials and create new opportunities for biomedical applications. The low covered polyrotaxane and polyurethane were characterized by FT-IR and 1H-NMR spectroscopies. In addition, and the elongation of polyurethane was shown through tensile strength measurement.
