Abstract (en)
[origin: CA2666171A1] The invention relates to a method for producing alkaline amides or imides of ethylenically unsaturated C3 to C6carboxylic acids by reacting amines th at contain at least one primary and/or secondary amino group and at least on e tertiary amino group with ethylenically unsaturated C3 to C6 carboxlic aci ds to form an ammonium salt and said ammonium salt is subsequently converted into the alkaline amide or imide by means of microwave radiation, with the proviso that the primary and/or secondary amino group is devoid of alkoxy gr oups.
