A series of new bis-benzocyclobutene-endcapped arylene ether monomers was prepared and characterized. Whereas 2,6-bis(4-benzocyclobutenyloxy)benzonitrile (BCB-EBN) could be prepared in good yield using the standard procedure (K 2 CO 3 / NMP/toluene/Dean-Stark trap/120ยฐC), other bis(benzocyclobutene)
## Abstract A series of poly(2โalkylโ6โphenylphenylene ether)s were prepared by the oxidative polymerization of 2โalkylโ6โphenylphenols. Their dielectric constants were approximately 2.5, whereas it was found that the phenyl group at the 6โposition clearly increased the __Q__ factor of the polymer
