| Abstract: | Hyperbranched poly(aryl ether ketones) with terminal fluorine atoms (OH: F = 0.48: 1.00) or hydroxyl groups (OH: F = 2.02: 1.00) have been obtained through the polycondensation of bis(4,4′-dihydroxydiphenyl-2,2-hexafluoropropane) with 1,3,5-tris4-(4-fluorobenzoyl)phenoxy]benzene in tetramethylene sulfone. Both polymers have M n = (7.1?7.3) × 103 and M w = (8.4?8.8) × 103 and are transparent in the near-IR region, in particular, at 1.30 and 1.55 μm. |
