FUNCTIONAL POLYARYLETHERS

摘要

Membranes comprising functional polyarylether having structural units of formula I are useful for hemodialysis and hemofiltration: wherein X is selected from Br, NR⁴R⁵, OOCR⁶, OR⁷, NR⁴CONR⁵R⁶, NR⁴COOR⁵R⁶ and combinations thereof; R¹, R² and R³ are independently at each occurrence CH₂X, H, halo, cyano, nitro, a C₁-C₁₂aliphatic radical, a C₃-C₁₂cycloaliphatic radical, a C₃-C₁₂aromatic radical or a combination thereof; R⁴ and R⁵ are independently H, a C_1-10 aliphatic radical, a C₃-C₁₂cycloaliphatic radical, a C₃-C₁₂ aromatic radical, or a combination thereof; R⁶ is H, a C_2-10 aliphatic radical, a C₃-C₁₂ cycloaliphatic radical, a C₃-C₁₂ aromatic radical or a combination thereof; R⁷ is OCH₂CH₂(OCH₂CH₂)_nOH or OOCCH₂(OCH₂CH₂)_nCH₃; Z is a direct bond, O, S, SO, SO₂, CO, phenylphospinyl oxide, alkenyl, alkynyl, a C₁-C₁₂aliphatic radical, a C₃-C₁₂cycloaliphatic radical, a C₃-C₁₂ aromatic radical or a combination thereof; a, b, and c are independently 1 or 2; and m, n and p are independently 0 or 1.
