Abstract

2, 6, 4'-Trifluorobenzophenone (TFB) was polycondensed with silylated 4, 4'- dihydroxybiphenyl (DHBP) or silylated bisphenol A in N-methylpyrrolidone by means of K2CO3 as catalyst and HF acceptor. At constant concentration (0.08 mol/L) the feed ratio was varied from 1.0/1.0 to 1.0/1.5. For polycondensations of DHBP cross-linking was observed for feed ratios above 1.0/1.1, whereas no gelation occurred with bisphenol A ...
