Polyimide-polyarylene polymers

1. A polymer composition comprising a copolymer polymerized from a monomer mixture of (a) one or more first monomers comprising a bis-imide compound comprising two or more aryl moieties substituted with ethynyl moieties and the two or more aryl moieties each having one or more polar substituents; and (b) one or more second monomers comprising two or more cyclopentadienone moieties;

wherein the one or more first monomers is a compound having Formula 1a,
