METHOD FOR WHOLLY POLYMERIZING AROMATIC POYLESTER

摘要

The aromatic polyester(I) is made by doing interfacial polymerization of bisphenol compound, aromatic dicarboxylic acid chloride, obtained from mixing terephtalic acid and isophtalic acid chloride at the molar ratio of 9:1-1:9, and molecular weight regulator such as paratertiary butylphenol(PTBP), under the phase transition catalyst such as tetrabutyl ammonium bromide(TBAB). The molar ratio of three components of the aromatic polyester(I) is 1:0.5:0.5.
