PROCESS FOR THE PREPARATION OF WATER-ABSORPTIVE FIBROUS MATERIAL |
| 摘要 |
<p>Aqueous solution of alkali or ammonium acrylate is applied to a prefabricated fibrous substrate, and the acrylate is subjected to polymerization in two steps, namely the first step in which the acrylate is polymerized by means of a radical polymerization initiator and the second step which is subsequent to the first step and in which the unpolymerized acrylate is polymerized by means of heat treatment at 100 - 250 DEG C.</p> |
