The resultant products were examined with thermtygravimetrie analysis (TGA) and high performance liquid chro- matography(HPLC). Thermogravimetry data shows that BDP decomposes at 375℃ when 5 % weight lost. Experiments results show that catalyst is preferably AICI3 and the amount of it is preferably 1% relative to bisphenol A by mole. POCl3/bisphenol A mole ratio is preferably about 5:1 to 6:1. Experiments unclosed that a seal apparatus is very important to the properties of product.展开更多
