摘      要：A novel diacid chloride, 2-（4-chlorocarboxyphenyl）-4-[3,5-dimethyl-4-（4-chlorocarbo-xylphenoxy）phenyl]-2,3-phthalazin-l-one 2, was synthesized and used for the preparation of polyarylates with inherent viscosities of 0.25-0.37 dL·g^-1. The glass transition temperatures of polyarylates were in the range of 217-272℃. The temperatures at 10% weight loss of polyarylates were found to be in the range of 434-464℃ in nitrogen atmosphere and their structure was confirmed by FTIR and IH NMR. The amorphous polyarylates exhibited excellent solubility in a variety of solvents such as NMP, DMAc, DMF and chloroform.
