PROCESS FOR PREPARING COLOR-STABLE WATER-ABSORBING POLYMER PARTICLES WITH A LOW DEGREE OF NEUTRALIZATION |
| 摘要 |
<p>The present invention relates to a process for producing water-absorbing polymeric particles by polymerizing a monomer solution comprising at least one ethylenically unsaturated acid-functional monomer less than 55 mol % neutralized and drying the resulting polymeric gel by means of a heated gas stream in at least two temperature zones.</p> |
