The glass transition temperatures of polyarylates were in the range of 217-272 degrees C. The temperatures at 10% weight loss of polyarylates were found to be in the range of 434-464 degrees C in nitrogen atmosphere and their structure was confirmed by FTIR and H-1 NMR. The amorphous polyarylates exhibited excellent solubility in a variety of solvents such as NMP, DMAc, DMF and chloroform.
