Phase separation in a thermotropic copolyester via spinodal decomposition

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

Novel experimental evidence is presented for the phase heterogeneity of a thermotropic copolyester containing 50 % of p-hydroxybenzdic acid (HB). Characteristic phase morphologies accompanying spinodal decomposition in polymer blends can be detected. Fractionation and a NMR-analysis demonstrate that the copolyester contains two constituents which differ in their HB-contents.
