A polymer of formula (I): (see formula I) where: n is an integer from 10 to 5,000; m is an integer from 10 to 5,000; Ar1 and Ar3 are the same or different and are residues derived from a tetra-hydroxy aromatic monomer, the tetra-hydroxy aromatic monomer being (see formula II), (see formula III), (see formula IV), (see formula V), (see formula VI), (see formula VII), (see formula VIII), (see formula IX), (see formula X), (see formula XI) or (see formula XII) wherein R is the same or different and is H or a C1-C8 alkyl, C2-C8 alkenyl or C3-C8 cycloalkyl group; and, Ar2 and Ar4 are the same or different and are residues derived from a tetra-halogenated aromatic monomer, the tetra-halogenated aromatic monomer being (see formula XIII) or (see formula XIV) wherein X is F, Cl or Br, and R1 and R2 are the same or different and are (see formula XV),(see formula XVI),(see formula XVII),(see formula XVIII),(see formula XIX),(see formula XX),(see formula XXI),(see formula XXII) (see formula XXIII),(see formula XXIV),(see formula XXV),(see formula XXVI),(see formula XXVII),(see formula XXVIII) wherein y is an integer from 1 to 8; with the proviso that when Ar1 is the same as Ar3 and Ar2 is the same as Ar4, R1 and R2 are not both -CN is useful as a material for gas separation, vapor separation, adsorbents or catalysis. 2 |
