## Abstract Poly(arylene ether oxadiazole) telechelics with fluorine and hydroxyl end groups were synthesized by nucleophilic substitution polymerizations of 2,5‐bis(4‐fluorophenyl)‐1,3,4‐oxadiazole monomer with bishydroxy compounds containing C(CH~3~)~2~, C(CF~3~)~2~ and SO~2~ groups. Fluorote
New poly[(silylene)arylene] statistical copolymers with o-conjugated silicon and T-conjugated carbon main-chain units are reported. They are synthesized in single-stage reactions by the Wurtz-type co-condensation of a dichlorosilylene and a dibromoaryl. Soluble polymers have been prepared with symme
Copolymerizations of p-dichlorobenzene (DCB)/4-bromophenyl ether (BPE), DCB/4,4Ј-dibromobiphenyl (DBB), and DBB/BPE pairs with sodium sulfide under high temperature (270 -290°C) utilizing N-methyl-2-pyrrolidinone (NMP) as solvent were carried out to give C(DCB/BPE), C(DCB/DBB), and C(DBB/BPE) copoly
Novel poly(arylene ether)s, poly(arylene thioether)s, and poly(arylene sulfone)s were synthesized from the dihydroxy(imidoarylene) monomer 1. The syntheses of poly(arylene ether)s were carried out in DMAc in the presence of anhydrous K 2 CO 3 by a nucleophilic substitution reaction between the bisph
