“…In chain‐growth condensation polymerization for linear poly( m ‐benzamide)s, the monomer is slowly added to a solution of initiator and LiHMDS,8, 9 so that the monomer concentration in the reaction mixture is lower than that in the chain‐growth condensation polymerization for poly( p ‐benzamide)s, in which the monomer was added at once into a solution of initiator and LiHMDS 2. Therefore, self‐condensation of the monomer in the synthesis of star‐shaped poly( m ‐benzamide)s from tetra‐functional initiator 2 would be suppressed under the same conditions that yield linear poly( m ‐benzamide)s. Thus, a variety of meta‐substituted monomers 3 were polymerized with 2 at 0 °C in the presence of LiCl13, 14 for N ‐alkyl and N ‐OOB monomers8 or N,N,N ′, N ′‐tetramethylethylenediamine (TMEDA)15–18 for N ‐TEG monomer10 according to the reported polymerization method for linear poly( m ‐benzamide)s (Scheme , Table 4).…”
