Synthesis of novel poly(hydroxyether terephthalate) via polyaddition of 2,5-difluoroterephthalic acid with aromatic bis(epoxide)s

Huang, Xiao-Song,Qing, Feng-Ling

, p. 1076 - 1082 (2008)

A novel and more reliable synthetic route to 2,5-difluoroterephthalic acid was developed. A series of new poly(hydroxyether terephthalate) were prepared by the polyaddition of 2,5-difluoroterephthalic acid with various aromatic bis(epoxide)s catalyzed by tetrabutyl ammonium bromide.
