## Abstract A novel class of polyamide‐quinazolinediones was synthesized by the polymerization of 2,2′‐disubstituted bis(1,3,4‐oxadiazolin‐5‐ones) with aromatic bis‐__o__‐amino esters in __m__‐cresol. The polymerization probably proceeded in the formation of ring‐opening adducts, which in turn were
