Abstract

Hyperbranched poly(ether sulfone) analogs with the 1,3,5-s-triazine moiety were prepared by the direct polymerization of AB$_2$type monomer, 2,4-bis(4-hydroxyphenyl)-6-(4-(4-(4-fluorobenzenesulfonyl)phenoxy)phenyl)-1,3,5-s-triazine (3). The selective reactivity of three chlorine atoms on cyanuric chloride toward nucleophiles provides an efficient route for the systematic synthesis of AB$_2$type triazine monomers and their hyperbranched polymers. The triazine rings influenced the structural and material characteristics of these hyperbranched polymers. The hyperbranched poly(ether sulfone) analog4 showed a glass transition at 295$^{\circ}C$. and was soluble in THF, 1,4-dioxane, and DMSO. An excellent thermal stability of polymer 4 was exhibited by a TGA analysis, which showed that 5% weight loss occurred at 480$^{\circ}C$.
