Abstract

A new linear 10-undecenoic acid-based diol and a chain extenders with 12C dangling chain length were synthesized via thiol-ene coupling and esterification reaction. In order to investigate the effect of the 10-undecenoic acid-based diol chain extender, the mole percent of the 10-undecenoic acid-based diol chain extender to the whole chain extender ranged from 0 to 100% (0%, 35%, 65%, 100%). The thermal and crystal properties of 10-undecenoic acid-based polyurethanes were characterized by differential scanning calorimetry (DSC) , thermogravimetric analysis (TGA) and (X-ray diffusion) XRD.The results show that with the increasment of dangling chain content, the glass transition temperature (Tg) and melting temperature (Tm) of polyurethane decreased obviously while the crystallinity decreased first and increased later.
