| titleOfInvention |
Process for making poly-alpha-oxyacrylic acid and its alkali metal salts |
| abstract |
Production of poly- Alpha -oxyacrylic acid by contacting a solution of Alpha -chloracrylic acid with one or more radicalyielding polymerization catalysts, heating and thereby hydrolyzing the resulting poly- Alpha -chloracrylic acid in queous solution with the resultant precipitation of solid polyAlpha -oxyacrylic acid and separating the poly- Alpha -oxyacrylic acid. More particularly, and aqueous Alpha -chloracrylic acid solution is contacted with the radical-yielding polymerization catalysts for a period of at least 30 minutes and, while leaving the resulting poly- Alpha -chloracrylic acid unseparated, it is heated for a period of at least 1 hour to temperatures within the range 80* and 110*C. |
