during polymerization. Condensation of BCP26C8 (1b) with ODA (2) and m-BAPPO (4) gave two new poly(amide crown ether)s, 3b and 5b, which were soluble in dipolar aprotic solvents. However, the GPC traces of aramides 3b and 5b exhibited bimodal behavior indicative of two distinct molecular weight fractions, one very high, DPn > 800! Similarly the aramide 3c formed by condensation of BCP20C6 (1c) and ODA
