Abstract
Polyarylenes comprising as polymerized units a first monomer having two cyclopentadienone moieties and a second monomer having two or more alkyne moieties, wherein at least one alkyne moiety is directly bonded to a silicon atom are provided. Such polyarylenes are useful as dielectric materials in the manufacture of electronic devices.
