Abstract
Official abstract text for this publication.
Polyarylene polymers formed from an aromatic dialkyne monomer having a solubility enhancing moiety and having relatively high weight average molecular weights and a relatively low polydispersity show improved solubility in certain organic solvents and are useful in forming relatively thick dielectric material layers in a single coating step.
First claim
Opening claim text (preview).
What is claimed is: 1 . A polyarylene polymer comprising as polymerized units one or more first monomers comprising two or more cyclopentadienone moieties; and one or more second monomers of formula (1): wherein each Ar 1 and Ar 2 is independently a C 5-30 -aryl moiety; each R is independently chosen from H, and optionally substituted C 5-30 -aryl; each R 1 is independentl…
