systems (ring-opening of four-membered rings; (ii) intramolecular assistance, or both factors); (iii) use of moisture-sensitive and/or activation reagents (up to 2–3 equivalents; borate esters, dialkylformamide dialkyl acetals, AlCl3, AlMe3, HCl). Examples of transamidation from the Stahl's group provided an elegant possibility of preparing amides under mild † This paper is dedicated to Prof. Victor

Process for the preparation of imidized acrylic polymers which comprises polymerizing acrylic monomers in the presence of at least one modifier chosen among those having the formulae:
and heating the thus-obtained polymer at a completing temperature higher than its melting temperature.
