NUCLEATION ACTION OF THERMOTROPIC LIQUID CRYSTAL POLYMERS IN THE BLENDS WITH PET

Received Date: 20 September 1990

The present work concerns the crystallization of PET accelerated by addition of thermotropic liquid crystalline polymers (TLCP)based on two aromatic copolyesters: PHB/PET (60:40 ) and PHB/HDA/2,6-DNA /IPA ( 50:25 : 12.5 : 12.5 ). The investigation has been made by measurements of the cold-crystallization and melt-crystallization temperatures by DSC and of the changes of density and depolarizing light intensity during the isothermal process. In addition, the morphology of selectively etched surface of compressing pellets proved the presence of crystalline fibrillar structure,it can be supposed to have grown up form the micelle nucleus based on bundle of rigid TLCP chains.
