THE SPHERULITE-LIKE STRUCTURE OF MAIN CHAIN THERMOTROPIC AROMATIC COPOLYESTERS*

Received Date: 5 January 1998

A new spherulite-like structure of main chain thermotropic aromatic copolyesters formed insolution cast specimens was observed and was studied by means of polarizing microscopy, X-ray diffraction,SEM and IR spectrometry. Results indicate that the spherulite-like structure of main chain thermotropicaromatic copolyesters formed from the casting solution (phenol/Cl2CH2CH2Cl2) is not a real crystal but only ahigh oriented arrangement of the macromolecular chains as a spherulite. This resulted from the interaction between the needle-like crystal of phenol and the rigid mesomorphic groups of molecular chain.The parallel packuing of extended copolyester molecules along the needle-like crystal of phenol leads to the formation of the spherulite-like structure.
