海报摘要

Highly stretchable polymer have getting much attention because of their unique properties. In this study, a highly stretchable polymer was synthesized by crosslinking polyurethane with pre-synthesized polyrotaxane from polypropylene glycol (PPG) with low covered cyclodextrin (CD) which acts as both chain extender and crosslinker. Polyrotaxane was used to synthesized by threading beta cyclodextrin (β-CD) along the axis of PPG-diamine polymer backbone followed end capped with 2,4,6-trinitrobenzene sulfonic acid (TNBS). The synthesized polyurethane and polyrotaxane were characterized by 1HNMR and FTIR spectroscopies. Coverage of polyrotaxane was adjusted by mole ratio of PPG and β-CD. DSC and TGA were used to characterize thermal properties of polyurethane. Tensile test was also conducted to measure elongation and tensile strength.
