Method for producing anionic water-soluble polymer on the basis of bioacrylamide and acrylic acid |
| abstract |
Process for the production of anionic water-soluble polymer obtained by the polymerization of acrylic acid and acrylamide obtained by biocatalysed reaction, said process comprising the steps of preparing a diluted solution of acrylic acid by mixing acrylic acid and water wherein the mass ratio between acrylic acid and water is comprised between 95:5 and 70:30, preparing a diluted solution of bioacrylamide and water wherein the mass ratio between bioacrylamide and water is comprised between 60:40 and 10:90, mixing said diluted solution of acrylic acid with said diluted solution of bioacrylamide, neutralizing partially or totally the acid function of acrylic acid and polymerizing the resulting mixture. |
