STUDY ON THE UCST AND LCST IN PHB/PBHE-SOLVENT SYSTEM

Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun, 130022

Received Date: 23 September 1994

Upper and lower critical solution temperature (UCST and LCST) behaviours have been examined for solution of PHB/PBHE blends in chloroform and chlorobenzene.Polymer-Solvent systems prepared with various solvents and concentrations were found to possess UCST and LCST characteristics.PHB/PBHE solution in chloroform displayed greater miscibility temperature region than that of the blend in chlorobenzene,but the relative tendency of both UCST and LCST were similar.
