A process for the modification of alkyl halogenated polyarylenes with a derivative compound comprising the steps of forming a mixture of the derivative compound with a phase transfer catalyst, wherein the derivative compound has the formula H－Z or M－T and Z is derived from a compound selected from the group consisting of water or alcohols, thiols, amines, iminos and imides containing at least one O, N or S atom bonded to the H, M is Na or K and T is derived from a compound selected from the group consisting of cyanides, iminos, imides, carboxyls and hydroxyl; combining the mixture with the alkyl halogenated polyarylene in an organic solvent to form a second mixture; agitating the second mixture until the desired degree of substitution has taken place and thereafter separating the modified polyarylene which contains a Z or a T group.

A process for the modification of alkyl halogenated polyarylenes with a derivative compound comprising the steps of: forming a mixture of said derivative compound with a phase transfer catalyst, wherein said derivative compound has the formula H－Z or M－T and Z is derived from a compound selected from the group consisting of water; aromatic, aliphatic, cycloaliphatic, amino and sulfonyl alcohols; aryl, aralkyl, aliphatic and cycloaliphatic thiols; heterocyclic amines; and heterocyclic imides and iminos which contain at least one O, N or S atom bonded to said H; M is Na or K and T is derived from a compound selected from the group consisting of cyanides; heterocyclic imides and iminos; carboxyls and hydroxyls; combining said mixture with said alkyl halogenated polyarylene in an organic solvent to form a second mixture, said alkyl halogenated polyarylenes having the formula [Figure] where R is a C1 to C10 aliphatic or a C5 to C7 cycloaliphatic radical or an aryl radical having the formula [Figure] wherein each R1 is independently a C1 to C10 aliphatic radical and p is an integer of 0 to 4; X is a halogen such as F, Cl, Br and I; A is hydrogen, halogen, an aliphatic or an aryl radical; Y is a divalent oxygen or sulfur atom or a carbonate group and n is an integer of from about 75 to about 10,000; agitating said second mixture until the desired degree of substitution has taken place and thereafter; separating the modified polyarylene which contains a benzylic substituted Z or a T group in place of the halogen. A process for the separation of gases from a mixture containing at least two gases into two fractions, one fraction being enriched with at least one of said gases and the other fraction being depleted in same, comprising the step of: contacting the gaseous mixture with a semipermeable membrane in such a manner that a portion of the gaseous mixture selectively passes through the membrane resulting in the enriched fraction being on one side of the membrane and the depleted fraction being on the other side of the membrane, said semipermeable membrane comprising a polyarylene compound having the formula [Figure] wherein each R is independently a C1 to C8 aliphatic or a C5 to C7 cycloaliphatic radical, an aryl radical having the formula [Figure] wherein each R1 is independently a C1 to C10 aliphatic radical and p is an integer of 0 to 4, A is a hydrogen, halogen, an aliphatic or an aryl radical; Y is a divalent oxygen or sulfur atom or a carbonate group; n is an integer or from about 75 to 10,000; and wherein Z is derived from a compund selected from the group consisting of water; aromatic, aliphatic, cycloaliphatic, amine and sulfonyl alcohols; aryl, aralkyl, aliphatic or cycloaliphatic thiols; heterocyclic amines; and heterocyclic imides and iminos containing at least one O, N or S atom; and T is derived from the group consisting of cyanide, heterocyclic imides and iminos, carboxyls and hydroxides.
