Hyperbranched poly(benzyl ether) analogs with the 1,3,5‐ s ‐triazine moiety were prepared by direct polymerization of AB 2 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.
