SYNTHESIS OF AROMATIC POLYETHERS BY SCHOLL REACTION .6. AROMATIC POLYETHERS BY CATION RADICAL POLYMERIZATION OF 4,4'-BIS(1-NAPHTHOXY)BIPHENYLS, 3,3'-BIS(1-NAPHTHOXY)BIPHENYLS AND 2,2'-BIS(1-NAPHTHOXY)BIPHENYLS AND OF 1,3-BIS(1-NAPHTHOXY)BENZENE

This paper reports the development of a novel method for the synthesis of fully aromatic polyethers. It consists of the cation-radical polymerization of bis(1-naphthoxy)aryls. The particular examples described in this paper refer to the polymerization of 4,4'-bis(1-naphthoxy)biphenyl(12),2,2'-bis(1-naphthoxy)biphenyl(13),3,3'-bis(1-naphthoxy)biphenyl(19), and 1,3-bis(1-naphthoxy)benzene (24). All polymerizations were performed in nitrobenzene with FeCl3 as oxidant. Aromatic polyethers with number average molecular weights up to 90 500 g/mol were obtained.
