Abstract

A new class of polyarylene co-polymers include repeating units comprising one or more arylene units having the general formula (--Ar--/--Y--).sub.n, where Y is a divalent group chosen from nil, --Z--, --Z--Ph--, and --Ph--Z--Ph--, where Z is a divalent group chosen from the group consisting of --O--, --S--, --NR--, --O(CO)--, --O(CO.sub.2)--,--(CO)NH(CO)--, --NR(CO)--, phthalimide, pyromellitimide, --CO--, --SO--, --SO.sub.2 --, --P(O)R--, --CH.sub.2 --, --CF.sub.2 --, and --CRR'--; Ph is phenylene (ortho, meta or para); and n is greater than 4. The co-polymers are useful as molding resins, and composite matrix resins, and where Ar is heteroarylene as ion exchange resins.
