Iṣelọpọ ti acrylamide monomer da lori acrylonitrile bi ohun elo aise, labẹ iṣe ti hydration ayase lati gbejade ọja robi ti monomer acrylamide, lẹhin distillation filasi, acrylamide monomer ti a ti tunṣe, monomer yii jẹ ohun elo aise fun iṣelọpọ ti poly444 acrylamide.
Acrylonitrile + (omi ayase/omi) → ni idapo → robi acrylamide → filasi → refaini → refaini acrylamide.
