Abstract

Hyperbranched poly(benzyl ether) analogs with the 1,3,5-s-triazine moiety were prepared by direct polymerization of AB2 type monomers, 2,4-bis(4-hydroxyphenyl)-6-(4-bromomethylphenyl)-1,3,5-s-triazine. The triazine rings influenced the structural and material characteristics of these hyperbranched polymers. In the hyperbranched poly(benzyl ether) analog, only the O-alkylated structure, instead of the C-alkylated branches, was observed, possibly due to the electron-withdrawing nature of the triazine ring which restrains C-alkylation on the phenyl group of the monomer. The triazine moieties play an important role in producing the structural regularity of hyperbranched poly(benzyl ether) analogs.
