| titleOfInvention |
Hydrophilic polymer based on acrylic acid and alkali metal acrylate, its method of preparation and its application as an absorbent, in particular of a physiological solution |
| abstract |
This polymer is based on acrylic acid and alkali metal acrylate; it has a degree of absorbency in respect of a physiological solution of 50 to 70 g/g, containing only 20 to 45% of acrylic acid, in molar proportions, and 80 to 55% of potassium acrylate. Its method of preparation is an oil-water suspension polymerization process which is carried out by introducing slowly, while being agitated, into the oil phase containing a protective colloid, a solution obtained starting from an aqueous solution of one or more polymerization initiators and an aqueous solution of the selected monomers, then eliminating any solvent until achieving a degree of dryness of 80±10% by weight, thus isolating the desired copolymer. This polymer is suitable for use as an absorbent. |
