The Effect of Catalysts and Solvents on the Condensation Polymerization of 2, 4, 6-Tribromophenolt

Abstract

An effectiveness of a number of combinations of aprotic dipolar solvents and catalysts was examined for the synthesis of polyroxy (2, 6-dibromo-1, 4-phenylene) (POBP) from 2, 4, 6- tribromophenol. The polymer was obtained in high yields in solvents such as DMSO, DMA, arid DMF; however, the yield was poor in HMPA or CH, CN. The catalysts for the polymeriztion of 2, 6-xylenol, except for iron salts, were also found effective for the synthesis of POBP. Copp
