ABSTRACT:
The present invention is directed to novel poly(arylene ethers), their synthesis and use in electronics applications as low dielectric insulating layers such as spin-on materials in integrated circuits. The polymers have repeating units of the structure: ##STR1## wherein m=0.2 to 1.0; and n=1.0-m; and Ar.sub.1, Ar.sub.2 and Ar.sub.3 are individually divalent arylene radicals selected from the group consisting of; ##STR2##
